1. Are the inside angles of all hexagons equal to 120o?
Only if it is a regular hexagon. This is a hexagon with all sides of equal length.
2.What is a REGULAR polygon?
A REGULAR polygon is a polygon with sides of equal length and angles of equal size.
3. Is it possible for a polygon to have an interior angle greater than 180o?
|
Yes. This type of polygon is called a concave polygon. |

4. How are the outside angles of a regular polygon, such as an octagon, calculated?
The outside (exterior) angles of any polygon always add up to 360o.
For a regular octagon, each of the eight exterior angles is 360o divided by 8 = 45o
5. Are there special names such as HEXagon for all polygons?
No, once we get pass the 12-sided dodecagon, we start writing them like this 13-gon, 14-gon etc.
