In particular this is true for regular polygons with evenly many sides, in which case the parallelograms are all rhombi. For the regular decagon, m=5, and it can be divided into 10 rhombs, with examples shown below. This decomposition can be seen as 10 of 80 faces in a Petrie polygon projection plane of the 5-cube.


List of polygons. Jump to navigation Jump to search. A pentagon is a five sided polygon. A regular pentagon has 5 equal edges and 5 equal angles. In geometry, a polygon / ˈ p ɒ l ɪ ɡ ɒ n / is traditionally a ...


A polygon is a two-dimensional plane figure with straight sides. These sides or segments do not intersect at any point. The parts of a polygon include the side, vertex, diagonal, interior angle and exterior angle.


A 10-sided polygon is known as a decagon. A polygon is a closed plane figure with many sides that connect at its endpoints. Two sides meet to form a vertex, and the sides never cross each other.


A regular polygon is a polygon that is both equiangular and equilateral. All sides are equal length placed around a common center so that all angles between sides are also equal. When the number of sides, n, is equal to 3 it is an equilateral triangle and when n = 4 is is a square.


9 Sided Polygon- Nonagon/Enneagon. 10 Sided Polygon- Decagon. What are the shapes called with the 'agon' at the end? Polygons. Polygons. Polygons. Polygons. share: Why is a octagon not a polygons?


A polygon is a plane shape with straight sides. 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 (straight sides) Not a Polygon (has a curve) ... Think Decagon has 10 sides,


After about 6 sides mathematicians usually refer to these polygons as n-gons. So your 13 sided polygon I would call a 13-gon. Cheers, Walter and Harley Go to Math Central. To return to the previous page use your browser's back button.


Convex - a straight line drawn through a convex polygon crosses at most two sides.Every interior angle is less than 180°. Concave - you can draw at least one straight line through a concave polygon that crosses more than two sides.At least one interior angle is more than 180°.


For polygons with 3 through 20 sides, simply add "gon" to the prefixes at the left (although a trigon is more commonly called a triangle and a tetragon, a quadrilateral!).
