### Pythagoras Growing Post

What is a Pythagorean Thereom

A pythogorean thereom is three unknown numbers: a , b and c. They obey the following relationship a2 + b2 = c2. A & B are both legs and C is the hypotenuse.

Part 2
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=?)

Part 3:
Explain how to solve a Pythagoras word problem. Use one of the examples we covered in class (Worksheet A, B, LeFrog or Bonus Problem).

Lefrog stands 1.5 meters from a wall where a fly is 2 meters up.
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 stretched 1.98 m to eat the fly.

A²= 1.3²
B²= 1.5²
C²= ???

A² + B² = C²
1.3² + 1.5² = C²
1.69 + 2.25 = C²
C² = 3.94
/c²=/3.94
/3.94=1.98

Part 4:
Now that you have seen many Pythagorean problems, create your own word problem.
