After reflection ΔABC turned into a triangle ΔA'B'C'. In these two triangles angles A and A' should be congruent. This means that options B and D are incorect.

If a scale factor of dilation is between 0 and 1, then ΔA'B'C' should be compressed to ΔA''B''C'' (all sides should have smaller lengths). Since in option C ΔA''B''C'' has greater dimensions, the correct choice is A.

10 = sidelength

Square the sidelength to find the area of the square. 10^2 = 100

Multiply that by 2 to find the area of the rectangle. 100*2 =
