Definition of Undecagon



An undecagon is an \(11\)-sided polygon. A polygon is a plane (flat) geometric shape with straight edges.

The names of most polygons are taken from Greek, so it is more correct to call an "undecagon" a "hendecagon".


The aim of this dictionary is to provide definitions to common mathematical terms. Students learn a new math skill every week at school, sometimes just before they start a new skill, if they want to look at what a specific term means, this is where this dictionary will become handy and a go-to guide for a student.
