Answer: $\overline{QC}\cong\overline{Q'C'}$ and $\angle{ACQ}$ is a right angle .

Step-by-step explanation:

Given : A reflection is a transformation that maps point Q in a figure over a line, AB, such that for point C at the intersection of AB and QQ'.

We know that reflection creates a image equidistant from the line of reflection.

Thus, $\overline{QC}\cong\overline{Q'C'}$

Also in reflection , a line drawn from the point is perpendicular to the line of reflection.

Therefore, $\angle{ACQ}$ is a right angle
