Pythagoras Theorem

hell18

to work out a traingle side e.g. 5²

is it we first times the 3 by its self to get 9 and then we times the 4 x 4 to get 16. then we take away the difference to get 5²?

9 + 16 = 25

Formula
3² + 4² = 5²

is this correct?

What you said was a little confusing, but here is a link to a simple statement of pythogrean's thereom:

To work out the hypoteneuse's (the side which does not end in a 90 degree angle) length, you square the first side and add it to the square of the second side. Then take the square root of the third side.

a² + b² = c²

3² + 4² = c²

9 + 16 = c²

c²= 25

c = [squ]25

c = 5
