- A line of symmetry is a line that divides a shape exactly in half. They are drawn with a dashed line. Lines of symmetry can be found by folding a shape in half or using a mirror. Each side of the line of symmetry will look exactly the same. For example, a square has 4 lines of symmetry. Lines of symmetry look like dashed lines.

Here you will learn about lines of symmetry, including symmetry properties within polygons, angle properties, and symmetry of different line graphs. Students first learn about line symmetry in grade 4 with their work with 2D shapes in geometry.

We have a number of figures in mathematics that are so evenly balanced n different sizes and shapes. Let us observe the following figures – We can observe that for each figure the one half on one side of the dotted line is exactly identical to the one half on the other side of the dotted line. In other words, we can say that the two halves are mirr...
We say that a given line has a line of symmetry or it is symmetrical about a lineif the line divides a given figure into two identical halves. The line is called the axis of symmetry or line of symmetry.
There are two types of line symmetries according to which we can classify the symmetries in different geometrical figures. These types are – 1. Horizontal Lines of Symmetry 2. Vertical Line of Symmetry Let us discuss them in detail
A geometrical figure is said to have one line of symmetry if it is symmetrical about one line of axis only. Let us consider some examples.
A geometrical figure is said to have two lines of symmetry if it is symmetrical about two lines of axis only. Let us consider some examples.
A geometrical figure is said to have three lines of symmetry if it is symmetrical about three lines of axis only. Let us consider some examples.
A geometrical figure is said to have four lines of symmetry if it is symmetrical about four lines of axis only. Let us consider some examples.
A geometrical figure is said to have five lines of symmetry if it is symmetrical about five lines of axis only. Let us consider some examples.
A geometrical figure is said of having six lines of symmetry if it is symmetrical about six lines of axis only. Let us consider some examples.
A geometrical figure is said of having infinite lines of symmetry if it is symmetrical about infinite lines of the axis. Let us consider some examples.
Sep 24, 2024 · Symmetrical Figures. A shape or an object has symmetry if it can be divided into two identical halve. Some of the common examples of symmetrical figures are listed below in the figure.
Aug 3, 2023 · The line of symmetry is an imaginary line that divides a shape or an object into identical halves. It is also called the axis of symmetry or the mirror line since it divides the figure symmetrically. The diagram below shows how a line of symmetry divides a shape into identical halves that are mirror images.
This Maths article shows how to find lines of symmetry on shapes and practise drawing them.
What are lines of symmetry? Lines of symmetry are straight lines that divide a shape into two equal parts where one part is an exact reflection of the other. E.g. A rectangle has two lines of symmetry (LoS) shown below using a dashed line.
In order to draw/identify lines of symmetry you need to: Locate the center of the 2D shape. Draw a horizontal and/or vertical line of symmetry through the center of the shape. Draw a line from each vertex through the center to check for all lines of symmetry. State the number of lines of symmetry.
