The hole is 8m deep, so there’s no way you can climb out by yourself, so you look around and notice that there is a ladder laying on the ground beside you. You can’t lean the ladder directly against the wall because there is a pit of acid that is 4m long around the whole pit, kind of like a mote. So you have no choice but to lean the ladder 4m back. The ladder is long enough for you to get to the top of the hole. How long is the ladder?

Describe what a Pythagorean Triple is and use your perfect square chart from 1 squared to 10 squared to find another one other than 3,4,5. (Note: You need a picture, not simply text.)

A Pythagorean Triple is that 2 side lengths (also called legs- A and B) added together
equals the hypotenuse (C). Also they use perfect squares to figure the hypotenuse.
(Means no decimal answers, just a whole number) It satisfies the solution:
a squared(a2) + b squared (b2) = c squared (c2)

Using embeddable web 2.0, describe how to find the missing side of a Right Triangle using the Pythagorean Theorem, show how to solve both for a missing leg and the hypotenuse (note: you may use numerical examples ie. a=4 b=6 c=?)

First we take 2 numbers (a=6 and b=8) and solve it. Take both a and b and make it
a squared + b squared =c squared. In numbers: 6 squared + 8 squared = c squared
6 x = 36 and 8 x 8 = 64. Add them together because it has to satisfy a squared + b squared =c squared.
36 + 64 = 100. 100 goes into 10. So C = 10 and C squared equals 100.

This is a picture of a Pythagorem Triple. A pythagorem triple says that the legs ( a and b) and the hypotenuse (c) of a right triangle follows the equation, a2 + b2 = c2. so if you add the legs together, you'll get the hypotenuse. This also shows that if you add the small square with the medium sized square, you'll get the biggest square. It uses perfect squares to find out the hypotenuse.

I am going to explain how we solved LeFrog. First we had the question. Lefrog stands 1.5 meters from a wall where a fly is 2 meters up. If Lefrog's tongue comes out of his mouth 70 cm from the ground, how far does his tongue have to stretch to eat the fly?
LeFrogs tongue had to stretch 1.98 m to eat the fly.


To figure out this problem, you first look at the question and find out the lengths of the triangle to find the hypotenuse. The lengths of our triangle was 1.5 and 1.3. It was 1.3 on one side because of the calculations i did on the top left corner. We then had to find out the length of LeFrogs tounge. We then used our formula ( a2 + b2 = c2 ). We used this formula, when we got to c, we used our calculators to find the sqaure root of the number. Finally, we found the answer to how far LeFrogs tounge had to stretch to eat the fly.

His tongue had to stretch 1.98 m to eat the fly.
>> click for bigger picture.

What we did to figure out the answer was we gathered our information about the triangle such as the lengths of the the sides a and b to figure out the hypotenuse c which was the tongue of Lefrog. We then made our formula for the answer so we found out the numbers of the square roots of a and b and added them to figure out c. When we figured out c we had to find the square root of it and we used calculators for that so it would be easier and after we had our answer for c and we figured out how long Lefrogs tongue had to stretch.

Pythagoras Growing Post

A Pythagoras triple is like a mathematical equation which consists of a² + b² = c². You will have 3 perfect squares and if you add them together you will get a perfect square number. In the middle of the Pythagorean triple in this example, is a right angle triangle (90 degree angle). Where one side or square has a², another b², then c². Here we used the perfect square chart where 6² + 8² = 10². You can also use 3² + 4² = 5².






How to Find The Missing Side of A Right Triangle
Using the Pythagorean Theorem



#1
Well first we have to find out what are our sides. Here the right angle always points to the hypotenuse or c which is 10. a= 4 and we have to find out what b is. So what we have to do is make sure we have a formula to start off with then we insert our numbers 4² +b² = 10². Now we have to square the numbers, 4² become 16 and 10² becomes 100. To find b we have to go 16+16 = 100-16. So b² = 84. The square root of 84 will equal b which is 9.16. b=9.16
----------------------------------------------------------------------------------------------
#2
First start off with a formula. a² + b²= c². Then we punch in our digits 4² + 7² = c².Now we have to square the numbers 16 + 49 = 65. To find c we have to find the square root of 65 which is 8.06.


















Lefrog

question: Lefrog stands 1.5 meters from a wall where a fly is 2 meters up. if Lefrog's tongue comes out of his mouth 70 cm from the ground, how far does his tongue have to stretch to eat the fly ?

One of the word problems we had to do in class was lefrog. We had to find out how far lefrog's tongue had to stretch to reach the fly. The question was just like a find the missing side question where you have to find out c. Although you have to convert cm to m. Which equals 0.7m then subtract that from 2m. Then we have to find a right triangle and draw it out with 1.3 as a and 1.5 as b and then we had to find c. After we squared the numbers we got 1.69 + 2.25 = 3.94 m . c² = 3.94 . The square root of 3.94 = c or 1.98.

Lefrog stands 1.5 meters from a wall where a fly is 2 meters up. if Lefrog's tongue comes out of his mouth 70 cm from the ground, how far does his tongue have to stretch to eat the fly ?

First gather your information that you have now :

- lefrog is 1.5 meters from the wall
- a fly is 2 meters up the wall
- his tongue comes out of his mouth 70 cm from the ground

It should look something like this :

Lets start with the formula, it would be a² + b² = c². once you got the formula you start to fill in your formula with the information that you have already. a² + b² = c² now turns into 1.3m² + 1.5m² = c². With 1.3m² + 1.5m² = c² you have to square off the squared numbers to add it and so it equals c². Multiply the base numbers by itself.1.3m x 1.3m = 1.69m, 1.5m x 1.5m = 2.25m. Now you add those numbers together to equal c². 1.69m + 2.25m = 3.94m . Now you know what c² equals you just have to find the square root of it. You have to use a calculator for this so you just punch in 3.94 and press the square root button and that gives us 1.98. So now our answer is LeFrog has to stretch his tongue 1.98 m to eat the fly.

We needed to find what c was so we first change 700 cm into 0.7m by dividing 100 into 700. We then needed to subtract 0.7 from 2m to get 1.3. With a formula a2 + b2 = c2 we plugged in the numbers so now it was 1.3 2 + 1.5 2 = c2. Then got their squared number 1.69 + 2.25 = c2. Then we added them together to get c2 which is 3.94. Since we had to find c not c2 we found the square root of 3.94 which is 1.98.

What is a Pythagorean Triple?

A Pythagorean Triple is a theory that says the two side lengths of a right angle triangle added together = the hypotenuse. The equation for that would be:

A² + B² = C²

To find the next Pythagorean Triple you look at your perfect Square chart to figure out which will work.

When you look at that you have to decide which two perfect squares added together will equal to another perfect square.

Right away you can tell that 6² + 8² = 10²

Then you can draw it out.
















You can also show it this way:

A² + B² = C²
6² + 8² = 10²

So first you should lay out the information you know.
>The Window is 25 ft above the ground
> There is a bus that goes out 10 ft on the ground
>You have to lean the ladder on an angle to get it to the house
>You're trying to figure out how long the ladder is


Then Try to Draw it out... Like this...















You probably noticed its is a right triangle. After noticing that you can use the Pythagorean theorem to solve what C is. ( C is always the side the right angle is pointing to with its corner.) Since you know that A² + B ² = C ² you plug in the info you know already

The Theorem
A² + B² = C²

Then you put the numbers in you know. A² & B² can be swapped it doesn't matter what number is where. I always put the smaller number in A.
10² + 25² = C²

Then you have to square the numbers as the theorem states. All you have to do is take the base number and multiply itself by itself.
10 x 10 = 100
25 x 25 = 625

Then you put those numbers into your equation.
100 + 625 = C²

Now all you got to do to find out what C² is is add the two numbers together.
100 + 625 = 725

That means that C² is 725
C² = 725

Now you have to find the square root of that number to find out how long the ladder is.
The square root of 725 is :

My Word Problem

>>Giggle the snake was slithering through the park one day to meet up with his friend Shout. They started to argue about who was longer. Giggle said he was so long that he could reach all the way from the edge of the tree stump to the sticker half way up the side of the outhouse. If the outhouse was 8 feet tall and the stump was 6 feet away from the outhouse how long would Giggle have to be to be able to reach from the bottom edge of the tree stump to the sticker on the side of the outhouse?

ANSWER:

(Highlight to see text. It's in white so you don't see it until you want to)

This is all in words becuase I didn't know how to hide pictures.

If the outhouse is 8 feet tall & the sticker was half way up that means the sticker is 4 Feet high. Now you know that one of the legs is 4. The right angle is where the ground meets the outhouse.

To the edge of the tree stump is 6 Feet. To find the hypotenuse or how long Giggle's is all you got to do is follow this:

A² + B² = C²

4² + 6² = C²

16 + 36 = C²

C² = 52

The square root of 52 is 7 3/15 or 7 1/3 OR 7.21

THATS ALL FOR NOW :)
