What is a mirror line?

Also, what is Mirror line in maths?

In math, reflection is the flipping of a figure or a point over a line of reflection called the mirror line. When we reflect something over a mirror line it does not change size, and it faces the other way.

One may also ask, how do you fully describe a reflection? A reflection is like placing a mirror on the page. When describing a reflection, you need to state the line which the shape has been reflected in. The distance of each point of a shape from the line of reflection will be the same as the distance of the reflected point from the line.

Also asked, does every figure have a mirror line?

Reflectional Symmetry A figure may have both horizontal and vertical lines of reflection. An object and its image are always at the same distance from the surface of a mirror, which is called the mirror line. Line symmetry and mirror reflection are naturally related and linked to each other.

Which word has Reflectional symmetry across a horizontal line?

The same is true of the letter M. Letters like B and D have a horizontal line of symmetry: their top and bottom parts match. Some letters, for example, X, H, and O, have both vertical and horizontal lines of symmetry. And some, like P, R, and N, have no lines of symmetry.
