I don't understand the Pythagreon Therom, can someone explain how it works please? I have a test today.

a squared + b squared = c squared.

Step-by-step explanation:

a is the length of the longest side to square that and b is the other side so square that too. so a squared is 4, b squared is 9, this means u have to add 9 and 4. then u get 13 and the square root of that is the length of c. happy to help

                                                / \

this side is a                         /     \                     this side is b length is 3

the length is 2                    /\

                                             this is unknown
