Solution
You can distinguish between a concave mirror and a convex mirror without touching them. When you look into these mirrors by bringing your face close to each mirror, they will produce an image of your face of different types.
A concave mirror will produce a magnified image of your face.
A convex mirror will produce a Diminished image of your face.
