A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.
What is the shape of dodecagon?
A dodecagon is a shape with 12 sides and 12 vertices (corners). It has 12 angles inside it that add up to 1800°.
What is a 10 sided circle called?
decagon
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon….Decagon.

What is a 19 sided shape called?
enneadecagon
In geometry, an enneadecagon, enneakaidecagon, nonadecagon or 19-gon is a polygon with nineteen sides.
What is a shape with 10000 sides called?
In geometry, a myriagon or 10000-gon is a polygon with 10,000 sides. Several philosophers have used the regular myriagon to illustrate issues regarding thought.
What do you call a 12 point shape?
Properties. Convex, cyclic, equilateral, isogonal, isotoxal. In geometry, a dodecagon or 12-gon is any twelve-sided polygon.

How big is one side of a dodecagon?
1 Perimeter = 12 x s 2 Length of one side: 17 mm 3 Perimeter: 12 x 17 mm = 204 mm
Can a dodecagon be both regular and irregular?
Dodecagons can be regular, meaning all interior angles and sides are equal in measure. They can also be irregular, with varying angles and sides of different measurements. If you ever try to draw a dodecagon freehand, you will no doubt make an irregular dodecagon.
How to find the area of a decagon?
Given here is a regular decagon, inscribed within a circle of radius r, the task is to find the area of the decagon. Below is the implementation of the above approach:
What are the properties of a dodecagon polygon?
A dodecagon is a type of polygon with these properties: No matter the shape, a regular polygon can have its exterior angles add to no more than 360°. Think: to go around the shape, you make a complete circle: 360°. So, divide 360° by the dodecagon’s twelve exterior angles. Each exterior angle is 30°.
