Given A”’ (-4,-6) and A”’ =Ro 180•(R y-axis(T <5,5> (A))) what is the coordinates of A?

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.

b is the correct answer
