Decagon Shape Examples In Real Life
Geometry is a fascinating branch of mathematics that deals with shapes and their properties. One such shape is the decagon, which is a ten-sided polygon. The decagon can be found in many real-life objects and structures. In this article, we will explore some examples of the decagon shape in the world around us.
Architecture
The decagon shape can be seen in many architectural structures. One such example is the Dome of the Rock in Jerusalem, which is a famous Islamic shrine. The shrine has an octagonal base and a decagonal drum, which supports the dome. The decagon shape is also used in many buildings and monuments around the world, such as the United States Department of Defense headquarters in Virginia and the Palace of Westminster in London.
Nature
The decagon shape can also be found in nature. For example, starfish have a decagonal shape, with ten arms radiating out from a central disk. The shape is also seen in some types of crystals, such as garnets and emeralds. The decagon shape can also be seen in the arrangement of petals in some flowers, such as the dahlia.
Mathematics
The decagon shape has many interesting mathematical properties. For example, the interior angles of a regular decagon add up to 1440 degrees. The perimeter of a regular decagon can be calculated using the formula P=10s, where s is the length of one side. The area of a regular decagon can be calculated using the formula A=(5/4)s²(√5+2), where s is the length of one side.
Art
The decagon shape has been used by many artists throughout history. One famous example is the decagonal room in the Palazzo dei Normanni in Palermo, Italy. The room is decorated with intricate mosaics and is considered one of the finest examples of Arab-Norman art. The decagon shape can also be seen in many works of Islamic art, such as tiles and carpets.
Sports
The decagon shape is used in some sports, such as track and field. The decathlon is a ten-event competition that includes running, jumping, and throwing events. The shape is also used in some sports equipment, such as the shape of a soccer ball, which is made up of twenty hexagons and twelve pentagons.
Technology
The decagon shape is used in some technological applications. For example, the shape is used in some computer graphics programs to create three-dimensional objects. The shape is also used in some types of industrial sensors, such as proximity sensors, which use a decagonal coil to detect the presence of metal objects.
Education
The decagon shape is used in education to teach geometry and other mathematical concepts. Students can learn about the properties of the decagon and how it can be used in real-life applications. The shape can also be used in art classes to teach students about the use of shapes and patterns in art.
Medicine
The decagon shape is used in medicine in some applications. For example, the shape is used in some types of implants, such as dental implants, to provide stability and support. The shape is also used in some types of medical tubing, such as catheters, to provide flexibility and ease of insertion.
Food
The decagon shape can be seen in some types of food. For example, star fruit, which is a tropical fruit, has a decagonal shape when sliced. The shape is also used in some types of chocolates and candies, which are often molded into various shapes, including the decagon shape.
Clothing
The decagon shape is used in some types of clothing and fashion accessories. For example, some earrings and necklaces are designed with a decagonal shape. The shape is also used in some types of buttons, which are often made in various shapes and sizes.
Transportation
The decagon shape is used in some types of transportation. For example, some types of wheels, such as those used on bicycles, have a decagonal shape. The shape is also used in some types of steering wheels, which are designed to provide a comfortable grip and easy handling.
Symbols
The decagon shape is used in some symbols and logos. For example, the logo for the United Nations features a decagonal wreath of olive branches. The shape is also used in some types of heraldry, such as the coat of arms of the city of Nijmegen in the Netherlands.
Conclusion
The decagon shape is a fascinating and versatile shape that can be found in many real-life objects and structures. From architecture to art, from mathematics to medicine, the decagon shape has many applications and uses. By understanding the properties of the decagon shape, we can gain a better appreciation of the world around us.
So, the next time you see a starfish, a soccer ball, or a piece of jewelry with a decagonal shape, remember the many ways in which this shape is used in the world around us.
