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.
