Excerpt from Key to Bradbury's Elementary Geometry and Trigonometry

All the divisors of 360, not less than 60, are 60, 72, 90, 120, 180, and 360; of which only 60, 90, and 120 can be the number of degrees in an angle of a regular polygon. These numbers represent the number of degrees in each angle of an equilateral triangle, a square, and an equilateral hexagon respectively.
