Which comparison is not correct?

A. -2 > -7

B. 1 -8
c. -3 > -8
D. 6 > 5

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

1/4 is the answer if i recall correctly.
