You can’t tile the Euclidean plane with regular octagons. I guess even though these shapes have eight sides each, they’re really just parallelograms or rectangles in disguise. The underlying pattern of this tiling is just a grid. These octagons have four pairs of parallel sides.

How to construct a perfect octagon?

Start with a square.

  • Find the center of square by drawing the two diagonals. Set the span of your compass from one corner to the center.
  • Set the pivot point of the compass in one corner and mark both sides from that corner.
  • Do the same for each of the other three corners.
  • Now each corner has two marks close to it.
