Pentagon G was dilated from the origin by a scale factor of one half to create Pentagon G′. Which statement explains why the pentagons are similar? Dilations preserve side length; therefore, the corresponding sides of pentagons G and G′ are congruent.
Dilations preserve betweenness of points; therefore, the corresponding sides of pentagons G and G′ are proportional.
Dilations preserve orientation; therefore, the corresponding angles of pentagons G and G′ are congruent.
Dilations preserve collinearity; therefore, the corresponding angles of pentagons G and G′ are congruent.
