Connecting Chords and Making Designs

Table of Contents || List of Constructions

Making designs in a circle and coloring them is great fun. Exploring the possibilities is what making grids is all about. Each point on the circle invites you to find connecting chords.

How many triangles can you count in addition to the sets you've identified?

Each point on this circle has at least four new chords that are not sides of the squares. Drawing eight sets of four chords, try to construct a grid that looks like the one below.
