A
decemyriagon is a
polygon with 100,000 sides and vertexes. All
internal angles on a regular decemyriagon measure almost exactly
180°. It derives it's name from the
Greek words "decemyria", "polloi", and "gonia",
meaning "100,000", "more than one", and "angle", respectively.
A decemyriagon is constructible with a
compass
and straightedge, but it would be complicated, even with the
tools because
A) There are so many sides and
there would be many steps
B) It appears
circular
C) Would be messy

But how much more can be said about a 100,000-sided shape?
