What Is A Shape With 12 Sides Called?
Have you ever wondered what a shape with 12 sides is called? In this article, we will explore the world of polygons and discover the name of this unique shape. Whether you are a student learning about geometry or simply curious about math, this article will provide you with all the information you need.
What is a Polygon?
Before we dive into the world of 12-sided shapes, let's first understand what a polygon is. A polygon is a two-dimensional shape with straight sides. The sides of a polygon are connected to form a closed shape. Polygons can have any number of sides, and each side is called an edge. The point where two edges meet is called a vertex.
What is a 12-Sided Polygon Called?
A 12-sided polygon is called a dodecagon. The name dodecagon comes from the Greek words dodeka, which means twelve, and gonon, which means corner or angle. Therefore, a dodecagon is a polygon with 12 angles or corners.
Properties of a Dodecagon
Now that we know what a 12-sided polygon is called, let's explore its properties. A dodecagon has 12 sides, 12 angles, and 12 vertices. The sum of the interior angles of a dodecagon is 1,800 degrees. Each interior angle of a regular dodecagon measures 150 degrees, while each exterior angle measures 30 degrees. A regular dodecagon has equal sides and angles, while an irregular dodecagon has unequal sides and angles.
Examples of a Dodecagon
Dodecagons can be found in various objects in our daily lives. For example, a soccer ball is made up of 12 pentagons and 20 hexagons, which together create a dodecahedron shape. The stop sign that we see on the road is also a dodecagon, with each side being an equal length.
Other Interesting Facts About Dodecagons
Here are some other interesting facts about dodecagons:
- A dodecagon can be divided into 54 triangles.
- The perimeter of a regular dodecagon with a side length of 1 unit is 12 units.
- The area of a regular dodecagon with a side length of 1 unit is approximately 5.5 units squared.
Conclusion
In conclusion, a shape with 12 sides is called a dodecagon. It is a polygon with 12 angles or corners and has various properties such as 12 sides, 12 angles, and 12 vertices. Dodecagons can be found in various objects in our daily lives such as soccer balls and stop signs. Understanding the properties of dodecagons is essential for students learning about geometry and for anyone who is curious about math.
So, now you know what a shape with 12 sides is called. Go ahead and impress your friends and family with your knowledge of polygons!
