Usage Examples
- (A geometric figure with eleven sides.)
- (An eleven-sided shape in design.)
Advanced Usage
- "Regular hendecagon": A hendecagon where all sides are equal in length and all interior angles are equal (each interior angle measures approximately 147.27 degrees).
- A regular hendecagon is difficult to construct with only a compass and straightedge because it is not a constructible polygon. (A precise, symmetrical eleven-sided shape.)
- "Concave hendecagon": A hendecagon with at least one interior angle greater than 180 degrees, creating an indentation.
- The irregular hendecagon had one concave angle, making it look like a star with a bite taken out. (An eleven-sided shape with an inward curve.)
