Interior angles of polygons This is just one of the six interior angles of this polygon.

P O L Y G O N S 2-6. DEFINITION A POLYGON is the union of segments in the same plane such that each segment intersects exactly two others at their endpoints.

Polygon Closed plane figure with at least three sides The sides intersect only at their endpoints No adjacent sides are collinear To name a polygon –Start.

Section 6-1 Polygons. Polygon Formed by three or more segments called sides. No two sides with a common endpoint are collinear. Each side intersects exactly.
