Triangle PQR was reflected using the rule (-x, y) and then dilated by a scale factor of 5 to create AP"Q"R". Which statement explains why the
triangles are similar?
O Reflections and dilations preserve orientation, therefore, the corresponding angles of APQR and AP"Q"R" are proportional.
O Reflections and dilations preserve collinearity; therefore, the corresponding sides of APQR and AP"Q"R" are congruent
O Reflections and dilations preserve side length, therefore, the corresponding sides of APQR and AP"Q"R" are congruent.
Reflections and dilations preserve angle measure, therefore, the corresponding angles of APQR and AP"Q"R" are congruent.
