In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, "eight angles") is a polygon that has eight sides...The area of a regular octagon can be computed as a truncated square...A regular octagon is constructible with compass and straightedge.


The I Ching (Wade-Giles) or "Yì Jīng" (pinyin), also known as the Classic of Changes, Book of Changes and Zhouyi, is one of the oldest of the Chinese classic texts.
