1440 degrees
To calculate this, you must find out how many triangles you can draw into the shape. Do this by taking the total number of sides (s) and taking away 2. This leaves you with how many triangles you can draw in the shape (t) from one vertex to another. (Not including outside lines!). Then, multiply the number of triangles in the shape by 180. This leaves you with how many degrees are inside that shape. (a)t = s-2a = t X 180This means there are 1800 degrees in a 12 sided polygon.

An undecagon is an 11 sided shape and its interior angles add up to 1620 degrees
10000000000 * * * * * The central angle in any closed shape must be 360 degrees. This is the measure of the angles about a point.
The three angles inside every triangle, no matter what shape or size it is, always add up to 180 degrees.
The whole shape has 540 degrees in it. To work out the amount of degrees in any shape - total degrees in shape = ((180 x number of sides of shape) - 360)
infinite.
