Are you wondering what the Pythagorean Theorem is? Well, in case you haven't heard of it, it is a formula used to find the hypotnues, also known as the longest side, of a triangle. Don't understand it that well, yet? The formula is a^2 + b^2= c^2. It is very simple to use once you learn and get the hang of it. Now I'm going to give you a simple problem for example. If Bob traveled on his bike 2 miles north to the store, went back to his starting point, and traveled west  for 2 more miles to his house, what is the distance from the store to his house?  The distance from his house to the store is hypotnues. If you draw it out, it would look like a right triangle. So then you use the formula. You replace a and b with 2, then you just solve to find c. It is pretty simple. 
     Another example would be: a ladder is stood next to a building at  5 feet. The distance of the whole area is 10 feet. How high is the ladder standing from the ground? The 5 feet would be the hypotnues, so you replace that with c. Then you replace b with 10, and you solve for a. Pretty simple!
