If a geometric figure undergoes a dilation with scale factor $k = 3$ , the lengths of its sides are tripled. What happens to the interior angles of the image?

True or False: If a figure is first reflected across the $x$ -axis and then translated by the vector $\begin{pmatrix}2\\3\end{pmatrix}$ , the final image is congruent to the original pre-image.

True or False: A reflection in the line $y = x$ results in an image that has the same orientation (e.g., clockwise vertex order) as the original pre-image.

If triangle ${PQR}$ is mapped to triangle ${P'Q'R'}$ by a dilation with a scale factor of ${k = 0.4}$ , which of the following properties is preserved?

A translation $T$ maps the point $(x, y)$ to $(x-3, y+5)$ . If the image of a point under $T$ is the origin $(0, 0)$ , what were the coordinates of the pre-image?

The angles are squared compared to the pre-image

The angles are three times the size of the pre-image

The angles remain the same as the pre-image

The angles are one-third the size of the pre-image
