Ancient mathematicians derive the geometry quantities of the five Platonic solids using the methods from the so-called "solid geometry". In 300 B.C., Euclid introduced solid geometry in book XI to XIII of his work, Elements. The compass-and-straightedge constructions of the Platonic solids were investigated in book XIII, as well as the existence of the five solids. On the other hand, in seventeenth century, these geometry quantities can be more easily computed using tools in analytic geometry, for example vector space, polar coordinate, symmetry, etc.
