Mirror reflection in mathematics, also known as symmetrical transformation, refers to the change of plane or space caused by the folding of a figure or object around an axis or plane. The figure or object is the same size and shape as the original figure or object, but the positional relationship is just the opposite. For example, if a square is folded around its center point, the figure obtained is the same size and shape as the original square, but the positional relationship is completely opposite.

Specular reflection also has many applications in real life. For example, symmetry principle is often used in building engineering to design the structure of buildings in order to obtain better support and beauty; In printing production, the method of reversing images is often used to produce beautiful visual effects.

In addition, specular reflection is also widely used in art, games and other fields. Through symmetrical visual effects, artists can create unique visual effects, which make the audience feel unusual and fascinating when enjoying their works. In the game, the use of symmetry helps to design elements such as game maps and props, and improves the playability and interest of the game.
