### Jenna's Pythagoras Growing Post

Part 1:

A Pythagorean Triple is a right triangle that uses a set of numbers (1, 2, 3, etc) that satisfy a2 + b2 = c2.
(no decimals)

<--- This is a Pythagorean triple. You can label each leg A or B, it doesn't matter which, but the hypotenuse is always labelled as C. (you can tell which is the hypotenuse because it is always opposite the right angle)

You can then place the numbers where the letters are. ( use numbers from perfect square chart )

Part 2:

Part 3:

You've just picked up a ground ball at first base, and you see the other team's player runnig towards thrid base.

How far do you have to throw the ball to get it from first base to thrid base, and runner out?

Part 4:

Mrs. Claire tells you that a right triangle has a hypotenuse of 13 and a leg of 5. She asks you to find the other leg of the triangle. What is your answer?

a=5
b=?
c=13
the formula for the missing leg would be: b squared=c squared-a squared.
b squared=13 squared-5 squared
b squared=169-25
b squared=144
square root of b squared=square root of 144
b=12

a²+b²-a²=c²-a²
b²=c²-a²
b²=13²-5²
b²=169-25
b²=144
square root of b²=square root of 144
b=12
