A Pentagonal Tiling of the Euclidean Plane We’ ve chosen one of the tile families from the Wikipedia article on pentagonal tilings (shown below) and we aim to see, using Mathematica, how this tiles the plane. In this tile we have: a = b, d = c+e angle(A) = angle(C) = angle(D) =120° We arbitrarily set the point “B” at the origin: pointB = 80, 0<; p1 = Graphics@8PointSize@LargeD, Red, Point@pointBD<, Axes fi TrueD -1.0 -0.5 0.5 1.0 -1.0 -0.5 0.5 1.0 We arbitrarily place the point “A” on the horizontal axis at (-2,0) and join point “A" and point”B” with a line:
