Overview

Symmetry is a beautiful and important concept in mathematics that we see all around us—in nature, art, architecture, and even letters of the alphabet. In this chapter, we explore what symmetry means, especially line symmetry or reflection symmetry. We learn how to identify symmetrical figures, find

Key Concepts

A line of symmetry divides

A line of symmetry divides a figure into two identical halves such that one half is the mirror image of the other. If you fold the figure along this l

When a figure has a line

When a figure has a line of symmetry, it is said to have reflection symmetry. Just like a mirror reflects your image, one side of the figure reflects

Two points are symmetric with respect

Two points are symmetric with respect to a line if the line is the perpendicular bisector of the segment joining them. One point is the mirror image o

Using basic geometrical tools like

Using basic geometrical tools like a ruler and compass, we can construct the symmetric point of a given point or draw the line of symmetry between two
