dodecagon --- 12 sides It must be regualar, that is, all sides must be equal and all 12 interior angles are equal. sum = 180(n-2) so each angle = 180(n-2)/n for 12 sides: each angle = 180(12-2)/12 = 150° you do the one with 20sides

Trigonometry/Geometry - Law of sines and cosines
In most geometry courses, we learn that there's no such thing as "SSA Congruence". That is, if we have triangles ABC and DEF such that AB = DE, BC = EF, and angle A = angle D, then we cannot deduce that ABC and DEF are congruent. However, there are a few special ...
