(II) The ray of light going through focus of a convex mirror becomes parallel to the principal axis after reflection.

(III) A ray of light which is incident at the pole of a convex mirror is reflected back making the same angle with the principal axis. Thus angle of incidence i is equal to the angle of reflection r.
