Lagrange's Four-Square Theorem Seen Using Polygons and Lines

Any natural number can be represented as the sum of the squares of four non-negative integers. For most numbers there are multiple representations. In this Demonstration the four integers (not squared) may be viewed using three different options.1. For each set of four numbers a polygon is displayed with vertices and .2. Each set is sorted from smallest to largest. The first two numbers a;;

1. Our notation for the polygon.

SOLVED: 8.35 (Lagrange's Four-Square Theorem) If n is a natural number, it can be expressed as the sum of four squares. A lattice in 4-space is a set of the form (x,y,z,w)
