The Groups of Regular Complex Polygons

Canadian Journal of Mathematics, 1961
The two-dimensional unitary space, U2, is a complex vector space of points (x, y) = (x1 + ix2, y1 + iy2), for which the distance between (x, y) and (x', y') is defined by . A unitary transformation is a linear transformation which preserves distance. A line is the set of points (x, y) satisfying some complex equation ax + by = c.

Regular and Irregular Polygons

1981
Polygons are figures with more than four straight sides. If the sides are all the same length the figures are said to be regular polygons, if they are not all the same length the figures are irregular polygons. A polygon with 5 sides is a pentagon 6 sides is a hexagon 7 sides is a heptagon 8 sides is an octagon 9 sides is a ...
