3. Polygons Box 1
Polygon – A Closed Figure in a plane that has 3 or more sides

4. Polygon Box 2 Concave – A side of the polygon is in the interior.
Convex- No sides of the polygon are in the interior.

5. Polygon Interior Angles (Box 3)
The sum of the measures of the interior angles of a convex n-gon is
(n – 2) * 180°

6. Interior Angles Examples
The sum of the interior angles of a convex polygon is 900°. Classify the polygon by the number of sides.

7. Polygon Exterior Angles (Box 4)
