Answer 2

Answer:

Rule

Any ray passing parallel to the principal axis will pass through the focus after reflection/refraction and vice-versa. (Shown by ray 1&2 in case of mirror and C, D, E & F in case of the lens)

Ray passing through the centre of curvature will reflect back undeviated. (Shown in A & B in case of lens)

Ray incident on the pole will reflect making an angle equal to the angle of incidence. (Shown by ray 3)

These rules are the same for both lens and mirrors except the third one is not applicable in case of a lens.

Sign convention

Sign above the principal axis is taken +ve and below principal axis is taken -ve

Sign in the direction of ray is taken +ve and opposite to the direction of ray is taken -ve
