For ΔABC, ∠A = x - 2, ∠B = x + 2, and ∠C = 2x - 20. If ΔABC undergoes a dilation by a scale factor of 2 to create ΔA'B'C' with ∠A' = 98 - x, ∠B' =

x

2

+ 27, and ∠C' = x + 30, which confirms that ΔABC∼ΔA'B'C by the AA criterion?

I think you'll understand when I say that when a triangle gets dilated the angle measures don't change
