What shape is a decagon?
ten-sided polygon
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°. A self-intersecting regular decagon is known as a decagram.
What shape is a nonagon?
nine sided shape
A nine sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners. The word nonagon comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.

What is an example of a decagon?
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.
What does a heptagon look like?
The heptagon shape is a plane or two-dimensional shape comprised of seven straight sides, seven interior angles, and seven vertices. A heptagon shape can be regular, irregular, concave, or convex. All heptagons can be divided into five triangles. All heptagons have 14 diagonals (line segments connecting vertices)

What does a decagon look like?
A decagon is a polygon whose internal angle is 1440°. A regular decagon is a decagon that looks like what is in the right (with a side length of 260px).
How many sides does the shape decagon have?
The shape of a Decagon: A decagon is a ten-sided polygon with ten vertices and ten angles. Here are some examples of a decagon.
What is the measurement of a decagon?
A regular decagon is a regular 10-sided polygon or 10-gon ie all 10 sides are of equal lengths. Each internal angle will always be equal to 144 degrees. Each internal angle = 1440/10 = 144 degrees.
How many diagonals in a decagon?
Thus, a decagon shape can be defined as a polygon having ten sides, ten interior angles and ten vertices. Based on the sides of a decagon, they are broadly classified into regular decagons and irregular decagons. A regular decagon has 35 diagonals and 8 triangles. We will learn more about them in the following section.
