A plane mirror is FLAT, whereas mirrors can be also convex (as with the back of a spoon) or concave (as is the case with the inside of a spoon). In other words, mirrors can be CURVED.

A plane mirror is a type of mirror that has a flat surface, whereas a mirror is a broad term used to describe any reflective surface. Plane mirrors reflect images with virtually no distortion, while mirrors can come in various shapes and sizes like concave or convex mirrors with specific reflective properties.
A concave mirror can create both real and virtual images, whereas a plane mirror can only create virtual images. A convex mirror can only create virtual images that are always diminished in size.
The distance between the image and the plane mirror is the same as the distance between the object and the mirror. Therefore, if the object is 15m away from the mirror, the image will also be 15m behind the mirror.
A plane mirror and a glass mirror both reflect light due to their smooth and flat surfaces. The difference is in the material used to coat the back surface - a plane mirror has a thin layer of metal, while a glass mirror has a thin layer of metal deposited on the back side of the glass.
The image formed by a plane mirror is a virtual, upright, and laterally inverted replica of the object. The distance between the object and its image in a plane mirror is twice the distance of the object from the mirror. The size of the image is equal to the size of the object.
