How can you identify the three types of mirrors without touching them?

Give reasons.

The three types of mirror can either be identified by their shape or the type of image it makes of a person standing in front of it.

We will look into the mirror by going close to it:
(i) If image is of same size and erect-plane mirror.
(ii) If image is of bigger size and erect – concave mirror.
(iii) If image is of smaller size and erect – convex mirror.
