What shape is a decagon?
A decagon is a 10-sided polygon. It also has ten vertices – which is where the sides meet – and ten angles. The regular decagon is probably the most recognizable one. It’s called a regular decagon because all its sides and angles are congruent, or equal in size.
What is a 9 sided shape?
How does Decagon look like?
A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440° . An irregular decagon has sides and angles that are not all equal or congruent.

Are all three sides equal?
A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.
Does a star have 10 sides?
They are regular polygons with five vertices and five edges. And a regular pentagon – or star – has … poly (means many) and gon (means sides). A star has five corners, and 10 sides.
What is an Undecagon?

What is the hardest shape?In geometry, the rhombicosidodecahedron, is an Archimedean solid, one of thirteen convex isogonal nonprismatic solids constructed of two or more types of regular polygon faces.It has 20 regular triangular faces, 30 square faces, 12 regular pentagonal faces, 60 vertices, and 120 edges.
What is a 56 sided shape called?
A polygon of 12 sides is called a dodecagon. NOTE: There are many more polygons, but the ones listed here are some of the most popular and most often taught in geometry classes. Polygons with more than 12 sides are usually referred to as n-gons. As in, a polygon with 56 sides is a 56-gon.

What is a 2 sided shape?
In geometry, a digon is a polygon with two sides (edges) and two vertices. A regular digon has both angles equal and both sides equal and is represented by Schläfli symbol 2.
Why can’t shapes have 2 sides?
Only if at least one side is curved. To have two different straight sides, you need them to meet at two different points. Since they are straight, this condition will mean the sides are the same line segment.
Is a line a two sided shape?
Strictly speaking, a side has to be a straight line (at least, in normal geometry). Hence, a semicircle is not regarded as a two-sided shape, as one of its “sides” would be a curve (ie not a side), and as a result the smallest number of sides a shape can have is three.
