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.
Triangle
3 sides
Quadrilateral
4 sides
Pentagon
5 sides
Hexagon
6 sides
Heptagon
7 sides
Octagon
8 sides

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.
