When is a figure said to have a line symmetry?
We can fold a picture in half such that the right and left halves match exactly
The two halves are mirror images of each other
A figure is said to have a line symmetry when we can fold a figure into two equal halves that are the mirror images of each other.The imaginary line or axis along which you can fold a figure to obtain the symmetrical halves is called the line of symmetry. There may be one or more lines of symmetry.
