## Some 2-tile tessellations with semi-regular angle-gons

Drag the large vertex A[1] to change the shape of the semi-regular angle-gon below with *n* = 3 and *k* = 1. Drag the centre of the circumcircle to enlarge or reduce.

Tessellation with equi-angular cyclic hexagon

Drag the large vertices A[1] and A[2] to change the shape of the semi-regular angle-octagon below with *n* = 4 and *k* = 1. Drag the centre of the circumcircle to enlarge or reduce.

Tessellation with equi-angular cyclic octagon

Investigate the transformations that can be used to create these tessellations, as well as the line and rotational symmetries of the resulting patterns.
