PLZ HELP Only do B) and C)

First frame is for b and second frame is for c

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.

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
