What is a real life example of a decagon?
Decagons in Everyday Life: Decagons can be commonly seen in various things in the surroundings, such as coasters, coins, umbrellas, drums, watches, cutlery etc. Also, a decagon is an intriguing form of polygons and is widely used while doing wall art.
Is a decagon a 10 sided shape?
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°.
Which is the best example of a decagon?
Sum of the Interior Angles of Decagon We know that the sum of the angles in each triangle is 180°. Thus, 180° × 8 = 1440°. Therefore, the sum of all the interior angles of a decagon is 1440°. Thus, one interior angle of a regular decagon shape is 144°.
What’s a 10 sided shape?
decagon
A decagon is a polygon that is easily identified by one key trait – it’s a 10 side shape with ten interior angles and ten vertices.
How many sides are there in decagon?
10
Decagon/Number of edges
How do you find the sides of a decagon?
Dale, In the diagram below the length of AC is 5 feet, the angle ABC has measure 144/2 = 72 degrees and the angle CAB is a right angle. |AB| = 5/tan(72o) = 1.62 feet. Hence the length of a side of the decagon is 2 × 1.62 = 3.24 feet.
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 does a Undecagon look like?
An 11-sided polygon (a flat shape with straight sides).

Nonagon/Number of edges
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.
