  • Line of Symmetry

What is a Line of Symmetry?

The line which divides the figure into two equal parts is called the line of symmetry or axis of symmetry.

When the exact mirror image or reflection of a line, object or shape gets created, we say there is symmetry.

The line of symmetry can be defined as the axis or imaginary line that passes through the centre of the shape or object and divides it into identical halves. 

Shapes or figures may have horizontal, vertical, both horizontal and vertical, infinite and no line of symmetry.

Some examples are shown below;

An Isosceles triangle has two sides equal and two angles equal with one line of symmetry.
