Answer:
If you look into a plane mirror, you can find that the size of the image is same as that of the object. If you look into a concave mirror, you can see an enlarged image when placed close and can see an inverted image when kept away. A convex mirror always forms a small and erect image.

We can distinguish these three mirror by just touching it by our hand through this method -
Walk towards the mirror. As you walk, observe the image formed at the repective mirrors very carefully.
Now, if the image in the mirror appear smaller then the mirror is a convex type of mirror.
And if the size of the image appears larger, the mirror is concave mirror.
If the size of the image is same, then the mirror is a plane type of mirror.
