In this game, students will quickly decide whether a geometrical figure is a polygon or not a polygon.
A polygon is a closed figure, formed by segments, and its sides do not cross.
The following figures are polygons.
The following figures are not polygons because they are not formed by segments.
The following figures are not polygons because they are not closed.
The following figure is not a polygon because its sides cross in the middle.
