What Is A Shape With 16 Sides Called?
Shapes are an essential part of our daily lives. We see them everywhere, from the buildings we inhabit to the clothes we wear. However, not all shapes are created equal. Some are more common than others, and some are so rare that they are virtually unknown to most people. One such shape is the one with 16 sides. In this article, we will explore what this shape is called and some interesting facts about it.
What is a Shape with 16 Sides?
The shape with 16 sides is called a hexadecagon. It is a polygon, which means it is a closed figure with straight sides. Hexadecagon is derived from two Greek words: hexa, which means six, and deca, which means ten. Therefore, a hexadecagon is a shape with 16 sides, 16 angles, and 16 vertices (corners).
Properties of a Hexadecagon
A hexadecagon has several properties that make it unique. Firstly, all of its internal angles add up to 2520 degrees. This means that each angle in a regular hexadecagon measures 157.5 degrees. Secondly, the sum of the exterior angles of a hexadecagon is 360 degrees. This means that if you were to walk around the outside of a hexadecagon, you would make a complete turn after 16 sides.
Regular vs. Irregular Hexadecagon
A hexadecagon can be either regular or irregular. A regular hexadecagon has equal sides and equal angles. In contrast, an irregular hexadecagon has sides and angles of different lengths and sizes.
Real-Life Examples of Hexadecagons
Hexadecagons are not commonly found in everyday life. However, there are some examples of hexadecagons in architecture and design. For example, the dome of the Florence Cathedral in Italy is an example of a hexadecagon. The dome is made up of 16 ribs, each of which corresponds to one of the sides of the hexadecagon.
How to Calculate the Area of a Hexadecagon
Calculating the area of a hexadecagon can be challenging, especially if it is irregular. However, there is a formula that you can use to calculate the area of a regular hexadecagon. The formula is:
Where A is the area of the hexadecagon, and s is the length of one of its sides. Cot is the cotangent function, and π is pi, which is approximately equal to 3.14159.
Conclusion
Hexadecagons are fascinating shapes that are not commonly seen in our daily lives. However, they have unique properties that make them interesting to study. We hope that this article has provided you with some insights into what a shape with 16 sides is called and some interesting facts about it. Remember, the next time you see a hexadecagon, you will know what it is called and what makes it unique!
