Ivanne's Pythagoras Growing Post

Part 1: Pythagorean Theorem
A pythagorean theorem states that the legs of the right triangle (a and b) and the hypotenuse obey the following relationship a2 + b2 = c2...

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

For example:
32+42=52
since 32 is 9 and 42 is 16...it equals to 52 which is 25...

You will know where the hypotenuse is because it is always on the opposite side of the right angle...

Part 2: Missing Hypotenuse

Part 3: 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: Question
A white board measures 30 inches long and 26 inches high. What is the diagonal measure of the white board?
