plane mirror

Draw a diagram illustrating that the minimum size of a plane mirror that shows you your whole body is half your height.
I don't understand. How does a plane mirror shrink your size? Isn't that for convex/concave?

Plane mirror doesn't shrink your size. But it is a fact that you usually don't need the whole mirror for you to see your whole body.

In order to draw the picture, first draw the size of object(your body), then fixing a place for plane mirror, draw light rays from your head and your leg on the plane mirror to your eyes. The distance between the two points on mirror is the minimum distance
