What's A 12 Sided Shape Called?
Welcome to our article about the 12 sided shape. If you've ever wondered what this shape is called or what it is used for, you've come to the right place. In this article, we will explore the definition, properties, and uses of the 12 sided shape.
Definition
The 12 sided shape is called a dodecagon. It is a polygon with 12 sides, 12 vertices, and 12 angles. The word dodecagon comes from the Greek words dodeka, which means twelve, and gonon, which means angle.
Properties
The dodecagon has several unique properties that make it an interesting shape to study. One of its most notable properties is that it can be divided into 12 congruent triangles. This means that each triangle has the same size and shape as the others.
Another property of the dodecagon is that the sum of its interior angles is equal to 1800 degrees. To calculate the measure of each angle, you can use the formula (n-2) x 180 / n, where n is the number of sides. For the dodecagon, this formula gives us an angle measure of 150 degrees.
Uses
The dodecagon has many practical uses in everyday life. One example is in the design of stop signs. Stop signs are often in the shape of an octagon, but some jurisdictions use a dodecagon instead. This is because the dodecagon provides more surface area for the word "STOP" to be printed, making it more visible to drivers.
The dodecagon is also used in the construction of regular dodecahedrons, which are 12 sided polyhedrons. These shapes are often used in architecture and design, such as in the construction of domes and cupolas.
Conclusion
In conclusion, the 12 sided shape is called a dodecagon. It has 12 sides, 12 vertices, and 12 angles. The dodecagon is an interesting shape to study because of its unique properties, such as being able to be divided into 12 congruent triangles. It also has practical uses in everyday life, such as in the design of stop signs and the construction of regular dodecahedrons. We hope you found this article informative and helpful in understanding more about the dodecagon.
