Answer 1

Explanation:

I don't know the way of drawing diagram from keyboard

Answer 2

Angle of incidences

Explanation:

The picture is missing in the question. Please refer to the attached picture for the image.

Ray AB is parallel to CD. The angle of incidence is 45 degree and marked on the picture for your reference. The two plane mirrors M1 and M2 are placed at right angles to each other. So we have four angle of incidence and they are equal.
