The statement correctly describes the resulting image, triangle is C. The reflection preserves the side lengths and angles of triangle. The dilation preserves angles but not side lengths.
Since the triangle is reflected across the y-axis and then dilated by a factor of centered at the origin. These are transformations which include
The operations performed on the triangle are the following
So, the reflection would preserve the side lengths and angles, but the dilation would only preserve the angles.
