Integer geometry: some examples and constructions. (English)
Math. Gaz. 81, No. 490, 18-28 (1997).
An integer polygon is a convex set of points in the plane such that no three are collinear and the distance between any two points is an integer; the measure used to order polygons is perimeter plus, the sum of all the edges and diagonals. This is generalized to integer polyhedra. The theorems of Pythagoras and Ptolemy are used to explore these polygons and polyhedra.
