What is a hendecagon in geometry?
What is a hendecagon in geometry?
A hendecagon is an 11-sided polygon, also variously known as an undecagon or unidecagon. A hendecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular hendecagon.
What does a Undecagon look like?
An 11-sided polygon (a flat shape with straight sides). The more correct name is Hendecagon.
What is the internal angle of a regular Undecagon?
Properties of regular undecagons
| Interior angle | 147° |
|---|---|
| Exterior Angle | 33° |
| Area | 9.365s2 approx |
How many side does a Undecagon?
11 sides
a polygon having 11 angles and 11 sides.
What is the order of rotational symmetry of an Undecagon?
Regular dodecagon It has twelve lines of reflective symmetry and rotational symmetry of order 12. A regular dodecagon is represented by the Schläfli symbol {12} and can be constructed as a truncated hexagon, t{6}, or a twice-truncated triangle, tt{3}. The internal angle at each vertex of a regular dodecagon is 150°.
What is the sum of exterior angles of Undecagon?
Answer: The sum of the exterior angles of a decagon is 360°.

Hendecagon/Sum of interior angles
What is the sum of the exterior angle of a Undecagon?
What is the measure of each exterior angle of a regular Undecagon If the measure of each interior angle is 150?
So each exterior angle of a regular dodecagon = 360/12 = 30 deg. Each interior angle = 150 deg.
What is the meaning of the word undecagon?
Here are all the possible meanings and translations of the word undecagon. A polygon with eleven sides and eleven angles. [L. undecim, eleven, Gr. gōnia, an angle.] A geometrical figure of eleven equal sides and angles.
What is the exterior angle of a regular undecagon?
33° To find the exterior angle of a regular undecagon, we use the fact that the exterior angle forms a linear pairwith the interior angle, so in general it is given by the formula 180-interior angle. See Exterior Angles of a Polygon
What are the properties of a regular undecagon?
Properties of regular undecagons. Interior angle. 147° . Like any regular polygon, to find the interior angle we use the formula #N# (180n–360)/n . For a undecagon, n=11. See Interior Angles of a Polygon. Exterior Angle.
