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.
