Problem : what three things must be true of adjacent angles adjacent angles must share a vertex and a side third, adjacent angles must not share any interior points. Constructions covers elementary methods related to perpendicularity, parallelism, bisectors, angles, polygons, circles and centers of a triangle. Golden ratios appears in many geometric constructions, including triangles and squares in circles, the pentagon and also in solids such as the dodecahedron.
In antiquity, geometric constructions of figures and lengths were restricted to the use of only a straightedge and compass (or in plato's case, a compass only a.
