ASAP PLS (40 POINTS)
∆PQR was translated and then dilated by a scale factor of 7 to create ∆P''Q''R''. Which statement explains why ∆PQR is similar to ∆P''Q''R''?
Translations and dilations preserve side length; therefore, the corresponding sides of
∆PQR and ∆P''Q''R'' are congruent.
Translations and dilations preserve orientation; therefore, the corresponding angles of ∆PQR and ∆P''Q''R'' are proportional.
Translations and dilations preserve collinearity; therefore, the corresponding angles of ∆PQR and ∆P''Q''R'' are congruent.
Translations and dilations preserve betweenness of points; therefore, the corresponding sides of ∆PQR and ∆P''Q''R'' are proportional.
