Center of a Polygon
Try this Adjust the number of sides of the polygon below, or drag a vertex
to note the center point of the polygon.
(If there is no image below, see support page.)
Regular Polygon case
In the case of
regular polygons
the center is the point that is equidistant from each vertex or corner.
It is also the center of the polygon's
incircle and
circumcircle.
Irregular Polygon case
Irregular polygons are not considered as having a center, since there is unlikely to be any one point
equally distant form each vertex. However, an irregular polygon can have a centroid, or center of gravity.
This is discussed further in the Coordinate Geometry volume.
