Dodecagon Construction and Tesselation


Step 1: Choose any point in the plane.
Step 2: Draw a circle (conceptually, at least) of radius R. Mark any point on that circle.
Step 3: Draw another circle of radius R, centered on the second point. Mark the two intersections of the two circles.
Step 4: Draw circles of radius R around the two new points, and mark the intersections of the circles.
Step 5: Draw another pair of circles around the two newest points, and mark their intersection with each other and with the first circle.
Step 6: The 6 points just marked inscribe a hexagon of side length R, centered on the first point.
