# Regular Bimorphic tilings of the first order

There are just two regular bimorphic tilings of the first order using squares and triangles. The one on the left has vertices SSTTT while the one on the right has vertices STSTT.

The tiles shown in bold colours make a single irregular tile which will cover the plane.

There is one first order regular bimorphic tiling using hexagons and triangles.

and one using octagons and squares
