In geometry, an enneacontahexagon (or enneacontakaihexagon) is a ninety-six-sided polygon or 96-gon. The sum of any enneacontahexagons's interior angles is 16920 degrees. ==Regular enneacontahexagon== The ''regular enneacontahexagon'' is represented by Schläfli symbol and can also be constructed as a truncated tetracontaoctagon, t, or a twice-truncated icositetragon, tt, or a thrice-truncated dodecagon, ttt, or a fourfold-truncated hexagon, tttt, or a fivefold-truncated triangle, ttttt. One interior angle in a regular enneacontahexagon is 176.25°, meaning that one exterior angle would be 3.75°. The area of a regular enneacontahexagon is: (with ''t'' = edge length) : The enneacontahexagon appeared in Archimedes' polygon approximation of pi, along with the hexagon (6-gon), dodecagon (12-gon), icositetragon (24-gon), and tetracontaoctagon (48-gon). 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Enneacontahexagon」の詳細全文を読む スポンサード リンク
