Polygons

• A polygon is a closed plane figure that is formed by three or more segments called sides.

• Each side intersects exactly with two other sides at a vertex.

Glossary • Segment is a part of a line, it has two endpoints.

• •

• Intersects are lines in a plane that meet at a point.

• Vertex – a point at which two sides of a polygon meet.

• Angle – A figure formed by two rays with the same endpoint.
