In the previous post, we have learned about **line symmetry**. In this post, we are going to learn about point symmetry, another type of symmetry.

If a figure is rotated 180 degrees about a point and it coincides with its original position, then it is said that the figure has point symmetry. The point of rotation is called the **point of symmetry**.

The figure below shows the point symmetric polygon *ABCDEF* rotated clockwise about *P, *its point of symmetry. The polygon outlined by the dashed line segments shows its original position. Continue reading
