HELP PLEASE! Square T was translated by the rule (x + 2, y + 2) and then dilated from the origin by a scale factor of 3 to create square T″. Which statement explains why the squares are similar?A. Translations and dilations preserve side length; therefore, the corresponding sides of squares T and T″ are congruent.B. Translations and dilations preserve orientation; therefore, the corresponding angles of squares T and T″ are congruent.C. Translations and dilations preserve betweenness of points; therefore, the corresponding sides of squares T and T″ are proportional.D. Translations and dilations preserve collinearity; therefore, the corresponding angles of squares T and T″ are congruent.
