Point Symmetry

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

Point Symmetry

origin symmetry, or point symmetry

Point Symmetry is when every part has a matching part:

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

 

Point Symmetry is also called Origin Symmetry, because the central point is also called the "Origin".

Examples

king of hearts
 
origin symmetry letters X H I S N Z
Many playing cards 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.
