Geometry Chapter 10 -1 Polygons

2
Convex Polygon – a polygon with a line containing a side with a point in the interior of the polygon.

3
Concave Polygon - a polygon WITHOUT a line containing a side with a point in the interior of the polygon

4
Interior Angle Sum Theorem The sum of the measures of the interior angles of a convex polygon is S = 180(n – 2) n = number of sides.

5
Interior Angle of a regular Polygon The measure of the interior angle of a regular polygon is n = number of sides.

6
Exterior Angle Sum Theorem The sum of the measures of the exterior angles of a convex polygon, one at each vertex is 360 0

7
Exterior Angle of a Regular Polygon The measure of an exterior angle of a regular polygon is n = number of sides.
