Since it has 11 sides, the sum of the interior angles is 180 degrees ( 11-2)= 180(9) or 1620 degrees.
regular hendecagon has internal angles of 147.27 degrees. The area of a regular hendecagon with side length a is given byA regular hendecagon is not constructible with compass and straightedge; this animation shows an approximation:
The sum of one angle is simply the measure of that angle.
The sum of all (interior) angles must equal 360 degrees
360 because ALL quadrilaterals have an angle sum of 360
