### Lester's Pythagoras Growing Post

Part 1: A Pythagorean Triple is a right angle triangle thats has and uses a set of numbers or letters, 1, 2, 3, or a, b, c. These numbers have to be a decimal, and have to fit the formula, a² + b² = c². An example of this are the numbers 3, 4, and 5... because 3² equals 9, 4² equals 16 and 5² equals 25.
a² + b² = c² (=) 3² + 4² = 5² (=) 9 + 16 = 25.

This is what that would look like as a picture...

As you can see, c² is always the hypotinuse. The hypotinuse is the the line connecting 3² and 4² or a² and b². Those lines are called legs.

Here is a diagram...

part 3: WORKSHEET A

You're locked out of your house and the only open window is on the second floor, 25 feet above the ground. You need to borrow a ladder from one of your neighbors. There's a bush along the edge of the house, so you'll have to place the ladder 10 feet from the house. What length of ladder do you need to reach the window?

Part 4: The free-throw line is 15 feet away from the basket. The rim is 10 feet above the ground. If you were to try and dunk from the free-throw line, how high and far will you have to dunk.

a=10
b=15
c=?
a squared+b squared=c squared
10 squared+15 squared=c squared
100+225=c squared
325=c squared
sqaure root of 325=square root of c squared
18.03=c
