exagon

— In the exagon, an equilateral triangle is made upon each of the sides. The octagon may be traced in the same manner as the exagon ; that is, by making an equilateral triangle upon each side : but as this construction is difficult in the practice, the author gives the following: find the square one ABCD as before; divide each of the sides AE, DE, into 3 = parts, and make upon the distance between the points of the division G, H, next to the point E, an equilateral triangle, which forms the angle GLH.
