in tessellations of polygons joined edge to edge we say two edges A and B are identical if two copies of the tessellations can be placed one on top of the other (after sliding, rotating, or flipping as necessary) so that the tessellations completely coincide when A and B are in the same position. d) Show tha there is only one tessellation that contains just regular dodecagons and equilateral triangles all with the same edge length and with the polygons joined edge to edge. Draw the tessellation and determine its maximum number of non identical edges.
