What do you call a shape with 11 sides?


Answer by  MathTeacher (299)

A shape with 11 sides is called a hendecagon or endecagon. It comes from the Greek word for "eleven", just as the decagon is named after the Greek word for 10. In general, after dodecagon (12-sided polygon), we name the shapes n-gons, where "n" equals the total amount of sides.

An eleven sided shape may be refered to as a "hendecagon". Some people may also refer to the same shape as a "undecagon".
