Pythagorean Theorem

“A right triangle has one side that is 3 units long and another side that is 4 units long. What is the length of the longest side? Imagine a park is shaped like a right triangle. You walk along one side that is 6 meters long, and then turn right and walk along another side that is 8 meters long. If you want to walk straight across the park to where you started, how far would you have to walk? ”
