Abstract

For instance, a graph is considered point symmetrical in relation to the origin when each point P of a graph, as shown in Figure I, has a corresponding point (also on the graph) under a reflection through so that . Or equivalently in the plane, each point P of the graph can be mapped onto a corresponding point (also on the graph) by means of a half-turn (a rotation through 180 degrees) around . Using the transformation formula for a half turn, it therefore follows that a graph is point symmetric in relation to the origin if ; in other words if it remains invariant under a half-turn around the origin.
