For the Pythagorean Theorem you must try to find a missing length of a right triangle. In this case you have to find the length of the hypotenuse.Which would be called C. To find the hypotenuse you add the 2 legs.Which can be called a or b. First you must square the lengths. Then add the the 2 squared amounts. You take that amount and square it and then you will have the missing length of the triangle.
Work:
a^2+b^2=c^2
16^2+12^2=c^2
256+144=c^2
400=c^2
\sqrt{400}=\sqrt{c^2}
20=c
