Answer:

The angle between two plane mirrors of an optical square is $45\textdegree$.

Explanation:

• The optical square belongs to reflecting instruments that measure angles by reflection.

• There are two mirrors placed vertically above the base at $45\textdegree$ each other.

• The optical square is based on the principle that if a ray of light undergoes two successive reflections in a plane at right angles to each of the two mirrors.

• The angle between the first incident ray and the last reflected ray is twice the angle between the two mirrors.
