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.
10 Οκτ 2022 · 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 ...
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".
List of polygons. A pentagon is a five-sided polygon. A regular pentagon has 5 equal edges and 5 equal angles. In geometry, a polygon is traditionally a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain.
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])
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.
