The pythagorean relationship is used for solving problems for finding the hypotenuse with 2 given legs. Also to figure out if the triangle is a right triangle or not.
1. Find The Missing Side Length.
c2 = a2 + b2
c2 = 52 + 122
c2 = (5x5) + (12x12)
c = 25cm2 + 144cm2
c = 169cm2
square root of 169 = 13cm
c = 13cm
2. Is This A Right Triangle? Show Your Work.
a2 + b2 = c2
62 + 82 = 112
(6x6) + (8x8) = (11x11)
36 + 64 = 121
100 /= 121
Not a perfect square because the legs don't make/equal the hypotenuse.
