The Pythagorean Theorem is useful because it tells you weather the triangle you have is a right angel triangle. The formula for the Pythagorean Theorem is a^2+b^2=c^2. For example if u have a right triangle and one side is 10 another is 8 and the another side is 13. So the first this you do is write the formula (a^2+b^2=c^2 ) then you plug in your numbers the two smaller number in the triangle are your legs and the highest number is call hypotenuse. So we you plug it is 10^2=100 ,8^2=64 and ,13^2=to 169 and when you add your legs you must compare it to your hypotenuse to see whither it is a right triangle or not. So the legs equal to 164 and the hypotenuse is 169.Therefor, it is not a right triangle. This is why the Pythagorean Theorem is important and useful.
