180*(11-2) = 180*9 = 1620 degrees.
Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)
An interior angle is the inside angle of a shape e.g quadrilateral, square
The sum is always 360 degrees. Note, though, that when the interior angle is convex, the measure of the exterior angle is negative.The sum is always 360 degrees.
