Note on Reflection of a line in line

Before we study about reflection of a line in a line.. let me help you go through about reflection.

What is a line of reflection?

A line of reflection is a reflected line, often off of a mirror. If a flashlight sends a beam of light at a mirror (the light is called the incident beam), the angle at which it hits the mirror will equal the angle at which the reflected beam of light (called the reflected beam), exits the mirror. This is called the Law of Reflection. This is why light is reflected from a mirror at the same angle at which light struck its surface.

Reflection of a line in a line:

The term ‘reflection of a line in a line’ in geometry, helps the determinations of reflection in a geometric point or dot is performed only through a given point or line. The basic ideas of reflection are the transformation of a point to a reflected point that is the equal length of the opposite side of a line. The transformation of reflections in two right angular axes produce a rotation of straight angle (180°), that is a half turn.
