Question

Triangle ABC is dilated using point P as the center of dilation, with scale factor 2. Constance states thatTriangle A'B'C' is congruent to Triangle ABC because the angle measures are congruent. Doreen disagreeΑ'АB'B*СРChoose the statement which best represents who is correct and why.ADoreen is correct, because angle measures don't have to be congruent for figures to be congruent.BConstance is correct because if corresponding angles are congruent, then two figures are congruent.

Answer 1

In the dilation of a polygon, the angles are preserved but the size of the sides are not equal.

Also, with dilation, the image and pre-image have the same shape but not the same size, hence they are similar but not congruent.

So, from the options given

Doreen is correct because angle measures don't have to be congruent for figures to be congruent.
