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

Point Symmetry is when every part has a matching part:
 the same distance from the central point
 but in the opposite direction.
(Note: its 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


Playing Cards often have Point Symmetry, so that they look the same from the top or bottom.

These Letters have 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: If cut at 45°, the two halves of this card are identical. In other words the view from 45°, and the opposite direction of 45° (which is 225°) are the same.
