Pythagoras Theorem

  1. 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?

    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
