A right triangle will have its longest side squared equal to the sum of the squares of the other 2 sides.
a) 6^2 + 8^2 = 10^2 ?36 + 64 = 100It IS a right triangle.
b) 1^2 + 2^2 = 5^2 ?1 + 4 does NOT equal 25 It is NOT a right triangle
c) 2^2 + 12^2  = 13^2 ?4 + 144 does NOT equal 169It is NOT a right triangle
