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? Dilations preserve side length; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent. Dilations preserve betweenness of points; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent. Dilations preserve orientation; therefore, the corresponding angles of ΔABC and ΔA′B′C′ are congruent. Dilations preserve angle measure; therefore the corresponding angles of ΔABC and ΔA′B′C′ are congruent.

so a dilatation by a scale factor of 2 what mean ? - the measures of the origin triangle was doubled
