and
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, 
Also in reflection , a line drawn from the point is perpendicular to the line of reflection.
Therefore,
is a right angle
