A dilation is applied to a triangle such that the sides of the image are 1.5 times the length of their corresponding sides in the original triangle. Then the angles of the image must be 1.5 times the size of the corresponding angles in the original triangle. Then the angles of the image must be two-thirds the size of the corresponding angles in the original triangle. Then the angles of the image must be 3 times the size of the corresponding angles in the original triangle. Then the angles of the image must be congruent to the corresponding angles in the original triangle.
