ΔABC was dilated from the origin by a scale factor of 2 to create ΔA′B′C′. Which statement explains why the triangles are similar?
A. Dilations preserve side length; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent.
B. Dilations preserve betweenness of points; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent.
C. Dilations preserve orientation; therefore, the corresponding angles of ΔABC and ΔA′B′C′ are congruent.
D. Dilations preserve angle measure; therefore the corresponding angles of ΔABC and ΔA′B′C′ are congruent.
