Expert Answer:

This can be done easily by studying the nature and size of the image and the relative movement of the mirror with respect to the image:
 
1. If the image is upright, of the same size as the object and it does not change in size when the mirror is moved, then the mirror is a plane mirror.
2. If the image is upright, magnified and it becomes inverted when the mirror is moved away from the face, then the mirror is a concave mirror.
3. If the image is upright and diminished and it remains upright when the mirror is moved away from the face, then the mirror is a convex mirror.
