Point Symmetry

It looks the same Upside Down!
(... or from any two opposite directions*)

Point Symmetry

origin symmetry

Point Symmetry is when every part has a matching part:

  • the same distance from the central point
  • but in the opposite direction.

It is also the same as "Rotational Symmetry of Order 2"

 

Note: Point Symmetry is sometimes called Origin Symmetry, because the "Origin" is the central point about which the shape is symmetrical.

Examples

origin symmetry letters X H I S N Z
Playing Cards often have
Point Symmetry, so that they look
the same from the top or bottom.
 
Each of these letters has
Point Symmetry, too!

*Same from Opposite Direction?

Yes, pick a direction, and anything with Point Symmetry will look the same from the opposite direction, too.

Example: When cut at 45° the two halves of this card are exactly the same.

In other words the view from 45°, and the opposite direction (which is 225°) are the same.
