What does a decagon shape look like?
What does a decagon shape look like?
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.
How many shapes does a decagon have?
ten
In geometry, a decagon is known as a ten-sided polygon or ten-gon. The sum of the interior angles of a simple decagon is 1440° and the sum of the exterior angles of a decagon is 360°….Decagon.

How does a Nonagon look like?
It has four equal sides and four right angles, each measuring 90 degrees. A regular nonagon is a nine-sided shape with equal sides and equal angles of 140 degrees each. Each interior angle measure of a regular nonagon is 140 degrees.
What is the meaning decagon?
Definition of decagon : a plane polygon of 10 angles and 10 sides.
What does a decagon symbolize?
The word “decagon” dates back to the 16th century, and is derived from the Latin word decagonum, wherein deca means ten and gonum means angles. So, the word decagon means ten angles.

How many sides are there on a decagon?
A decagon is a polygon with 10 sides and also 10 angles. Deca is of course a prefix denoting the number ten .
How do you find the exterior angle of a decagon?
To find the exterior angle of a regular decagon, we use the fact that the exterior angle forms a linear pair with the interior angle, so in general it is given by the formula 180-interior angle.
What is the exterior angle of a decagon?
Assuming the decagon is a regular polygon in which all sides are equal, each exterior angle will be 36 degrees. (Sum if all the exterior angles equals 360 degrees, ten in this case). Thus each interior angle which is supplementary to the exterior angle will be 144 degrees.
How do you calculate the area of a decagon?
The general formula to find the area of a regular decagon is as follows, Area of a decagon = 2.5 (a)(l) Where, a = side length of the regular decagon. l = length between two parallel faces. The next section gives us a clear view on how to calculate the area of a regular decagon.
