A regular polygon is a polygon in which all sides are equal and all angles are equal, Examples of a regular polygon are the equilateral triangle (3 sides), the square (4 sides), the regular pentagon (5 sides), and the regular hexagon (6 sides). As EA and ED are equal side lengths by definition of a regular pentagon, we know triangle DEA is isosceles, with angle DEA = 108 degrees and the two smaller angles equal to 36 degrees each. We know DAB = 72 degrees, so x = 90-72 = 18 degrees. So for example, in Book IV, where Euclid discusses regular polygons inscribed in a circle, we find the triangle, the square, the pentagon, the hexagon, and the regular 15-sided polygon, all of which can be constructed.
