_______ANSWER_________________

The rules used for drawing ray diagrams for the formation of an image by a concave mirror are:

Rule 1: If the incident ray is parallel to the principal axis then the reflected ray passes through the focus of the concave mirror.

Rule 2: If the incident ray passes through the focus of the concave mirror, the reflected ray is parallel to the principle axis

.

Rule 3: If the incident ray passes through the centre of curvature of the concave mirror, the reflected ray traces the same path.
