Proof #1

1. Take (n-2)180/n and make n=∞, one internal angle would equal 180.

2. The formula above only works for polygons.

3. The only shape that could ever satisfy the needs of (∞ -2)180/∞ =180 is a circle.

4. Saying this, because a circle has 360 deg. then a circle is considered a 2-sided polygon.

Proof #2

1. To find the internal angle of a shape you must find the least amount of triangles that can fit in it. (ex. 2 in square, 3 in pentagon)

2. A square has 2 triangles so they add up to 360 deg.

3. This means a circle is not 360 deg.

4. Taking (∞ -2)180/∞ =180 into account, the circle is now an infinite pointed shape with infinite deg.

Tell me what you think because this stuff fascinates me.
