In geometry, a hendecagon (also undecagon [1] [2] or endecagon [3]) or 11-gon is an eleven-sided polygon. (The name hendecagon, from Greek hendeka "eleven" and -gon "corner", is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim "eleven". [4] ) Regular hendecagon Individual polygons are named (and sometimes classified) according to the number of sides, combining a Greek -derived numerical prefix with the suffix -gon, e.g. pentagon, dodecagon. The triangle, quadrilateral and nonagon are exceptions, although the regular forms trigon, tetragon, and enneagon are sometimes encountered as well. Greek numbers

If your polygon has 11 or more sides, it's easier to write 11-gon, 14-gon, 20-gon. "100-gon", etc. But if you're really curious. Regular polygon formulas: sides, area, perimeter, angles If you want to calculate the regular polygon parameters directly from equations, all you need to know is the polygon shape and its side length: Area A hendecagon is an 11-sided polygon, also variously known as an undecagon or unidecagon. The term "hendecagon" is preferable to the other two since it uses the Greek prefix and suffix instead of mixing a Roman prefix and Greek suffix. Regular or Irregular A regular polygon has all angles equal and all sides equal, otherwise it is irregular Concave or Convex A convex polygon has no angles pointing inwards. More precisely, no internal angle can be more than 180°. If any internal angle is greater than 180° then the polygon is concave. ( Think: concave has a "cave" in it) Here is the list as a table of all the different regular geometric shapes of the 2D plane (table of n-sided polygon names): #. Name of the Polygon + Geometric Drawing. 1 side. monogon (impossible figure in Euclidean geometry) 2 sides. digon. 3 sides. triangle or trigon.
What is a hendecagon? Answered 11 Sided Shape Activities
A hendecagon is a flat shape with 11 straight sides. Regular and irregular hendecagons A regular hendecagon is a 11-sided shape where every side is the same length and every corner has the same angle. All regular hendecagons have the same shape, like this: An irregular hendecagon is a 11 sides shape where not every side and angle are equal. In geometry, a hendecagon (also undecagon [1]) is an 11-sided polygon. The name "undecagon" is often seen as incorrect, but the matter is up for debate. The Greek prefix 'hen', is preferable to the Latin 'uni' or 'un'. [2] A regular hendecagon has internal angles of 147. 27 degrees . The area of a regular hendecagon with side length is given by An 11-sided polygon is referred to as Hendecagon. It is derived from two Greek words 'Hendeka' which means eleven and 'gon' which means angles. Both words refer to the shape of an eleven-sided polygon. How are Polygons Named? The name of each polygon is made of two words. The first part of the word is influenced by the Greek meaning of the. Answer: 11 sided polygon is called Hendecagon. Let's look at a polygon with 11 sides. Explanation: A polygon is said to be regular if it has equal length on all of its sides and with equal angles at each vertex. Here is the regular polygon with 11 sides. Polygon with 11 sides is called hendecagon.

An 11-sided polygon known as a hendecagon may also go by the names undecagon or unidecagon. Since ; A regular polygon known as a regular hendecagon is a hendecagon with vertices evenly placed around a circle and all sides the same length. It has 11 sides and 11 vertices, making it a hendecagonal shape. There are a total of 11 angles that make. This is a list of two-dimensional geometric shapes in Euclidean and other geometries.

Create your account. View this answer. A shape that has 11 sides is called a hendecagon, undecagon, or an endecagon. These are all names for a polygon that has 11 sides and 11 angles. Polygon Calculator. Use this calculator to calculate properties of a regular polygon. Enter any 1 variable plus the number of sides or the polygon name. Calculates side length, inradius (apothem), circumradius, area and perimeter. Calculate from an regular 3-gon up to a regular 1000-gon. Units: Note that units of length are shown for convenience.

A polygon is a 2D shape with straight sides. To be a regular polygon all the sides and angles must be the same: Other Common Polygons These are 2D shapes, and they are polygons, but not regular polygons: Curved Shapes These are also 2D shapes that are not polygons because they have curves: 3D Shapes There are plenty of 3D shapes too! We get. So, the sum of the interior angles of an 11-gon is 1620 degrees. Regular 11-gons: The properties of regular 11-gons: All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1620 degrees (from above).
