Two Lines Of Symmetry - Vedantu

A figure which does not have any similarity between two halves is known as an asymmetrical figure. In an asymmetrical figure, none of the sides of the shape is equal.

You cannot fold the heart further to get the perfect symmetry. Hence, we can say that the heart shape has one and only one line of Symmetry. There are some figures wherein the lines of symmetry can be more than one. It is very important to understand the following points before studying the line of symmetry in detail.

1. If a figure or shape does not have a line of symmetry, it indicates that the shape or figure is asymmetrical.

2. Few shapes or figures have one line of symmetry, two lines of symmetry, or multiple lines of symmetry.

A circle can have an infinite number of lines of symmetry as it can be folded at any diameter to get the symmetrical halves. A square is said to have four lines of symmetry as its sides are the same, so the diagonal lines and vertical as well as horizontal lines divide a square. The equilateral triangle has three lines of symmetry whereas a scalene triangle does not have any line of symmetry as its all sides are different. An isosceles triangle has one line of symmetry as both of its sides are equal. A pentagon has five 5 lines of symmetry and a hexagon has six lines of symmetry.

Two Lines of Symmetry

Some figures can be divided into two equal parts with two lines. These shapes are said to have two lines of symmetry. The rectangle is an example of two lines of symmetry. A rectangle can be divided vertically, horizontally, or diagonally to get the two symmetrical parts. A rhombus also has two lines of symmetry. Two lines of symmetry can be a combination of vertical, diagonal, or horizontal lines. Letters such as H and X also have two lines of symmetry. An hourglass is also an example of two lines of symmetry.

A rectangle does not have a diagonal line of symmetry as opposed to a square as its sides are not the same. The rectangle can only have a vertical and horizontal line of symmetry.
