Definition
| Draw a kite shaped polygon on your paper somewhere. Notice that if you draw a segment connecting any two non-adjacent vertices that the segment only passes through the interior. We would classify the kite as a(n) ______________________________. |

Definition
If you connect points O and Y on the figure below with a line segment. The segment will pass through the exterior of POLY. For that reason we would classify POLY as a(n) ______________________________.

Term
| central angle (of a regular polygon) |
|
Definition
| The vertex of a(n) ________________________________________ lies at the polygon's center, and its sides pass through adjacent vertices of the polygon. |
|
|
Term
| interior angle (of a polygon) |
|
Definition
Any angle on the inside of a polygon that is formed by two segments that define the polygon is called a(n) ______________________________. |
|
|
Term
| exterior angle (of a polygon) |
