The image formed by a plane mirror is virtual, erect, same size as object, and laterally inverted ( left side appears right and right side appears left ).
Also, the virtual image is as far behind the mirror as the object is in front of the mirror.
A Plane Mirror
An erect but virtual image of same size but with lateral inversion
inverted image for eg take your spoon and look in it
Convex mirror forms a virtual image.

What type of image does a flat mirror form?Virtual image
A Plane Mirror
concave mirror
An erect but virtual image of same size but with lateral inversion
Concave mirrors
Usually as we say the details of the image we point out their, size, position, type and nature. In case of plane mirror, size = same size of the object position = at the same distance as the object is in front of the mirror type - erect one nature - virtual image. This means could be seen but not be caught on a screen.
inverted image for eg take your spoon and look in it
It forms a virtual, right side up, magnified image.
Convex mirror forms a virtual image.
Plane mirrors produce a virtual image.
