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.
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.
10 Οκτ 2022 · 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] [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".
Is it a Polygon? Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up). Polygon comes from Greek. Poly- means "many" and -gon means "angle". Types of Polygons. Regular or Irregular. A regular polygon has all angles equal and all sides equal, otherwise it is irregular.
This is a list of two-dimensional geometric shapes in Euclidean and other geometries. For mathematical objects in more dimensions, see list of mathematical shapes. For a broader scope, see list of shapes.
A hendecagon is an 11 sided shape with 11 corners. It is sometimes referred to as an 11-gon. In the 2D polygon family, it has one more corner/side than a decagon and one less corner/side than a dodecagon. This 11 sided shape is two-dimensional.
