You can put this solution on YOUR website! Is it possible to have a regular polygon with at least one 100 Degree angle.
---
If the polygon is regular all of the angles are equal.
---
If at least one angle is >= 100 the corresponding exterior
angles are <= 80.
---
Let the exterior angle be "x" where 0< x <80
---
Fact: The sum of the exterior angles is 360.
---
# of sides = 360/x >= 4.5
---
For example: if there are 5 sides the exterior angles are 360/5 = 72 degrees
and the interior angles are each 180-72 = 108 degrees.
----
All regular polygons with 5 or more sides have interior
angles greater than 100 degrees.
