Question

Triangle ABC is dilated by a scale factor of 1.5 to create triangle A'B'C'. Which of

the following it not a true statement?
A. The image is larger than the pre-image.
B. The orientation of triangle ABC is preserved.
C. Segment AB is congruent to segment A'B'.
D. The angle measures in triangle ABC are equal to the angle measures in triangle
A'B'C'.

Answer 1

C. Segment AB is congruent to segment A'B'.

Explanation:

Since ABC is being dilated by 1.5, it means that A'B'C will be bigger than ABC.

So, since A'B'C will be bigger than ABC, it sides will also be bigger than the sides in ABC.

And since the sides/segments are bigger than the original, they are not congruent (congruent means equal).
