APQR was translated and then dilated by a scale factor of 7 to create AP"Q"R". Which statement explains why APQR is similar to AP"Q"R"?
O Translations and dilations preserve side length; therefore, the corresponding sides of APQR and AP"Q"R" are congruent.
O Translations and dilations preserve orientation; therefore, the corresponding angles of APQR and AP"Q"R" are proportional.
Translations and dilations preserve collinearity; therefore, the corresponding angles of APQR and AP"Q"R" are congruent.
O Translations and dilations preserve betweenness of points; therefore, the corresponding sides of APQR and AP"Q"R" are proportional.
