polygon such as a square, regular hexagon, and an equilateral triangle. For example, use lots of coloured tiles to build a pattern like this: At the point marked by the arrow you could try asking questions like: If I took out one of the triangles, how do I know. #append the holey grid to the Total_Tess blank shpĪp.Append_management(hex_single, final_grid, "NO_TEST", "Join")Ĭreate_hex(hex_single, final_grid, level+1, int(area/3))Īp. This heptagon will not tessellate regularly because a heptagons interior angle. Try to question the children in such a way so as to lead them to explore this, perhaps by drawing their attention to a particular part of the tessellation.

Runs fine except when we get to levels 10 and beyond in the loop - it starts spitting out the wrong shape. We're creating a recursive search grid that digs down through data points so there's only 50 points per hex. Just wondering if anyone out there in the ArcMap world may know why our hexagonal tessellation outputs are coming out as Triangles and other shapes.
