A Shape With 14 Sides Is Called
Shapes are an essential part of our daily lives. We encounter them everywhere, from the natural world to the man-made environment. Understanding the names of different shapes can be useful in various ways, from mathematical calculations to artistic compositions. In this article, we will explore the name of a shape with 14 sides.
What is a Shape with 14 Sides Called?
A shape with 14 sides is called a tetradecagon. The word tetradecagon is derived from the Greek words "tetra," which means four and "deka," which means ten. Hence, tetradecagon literally means "fourteen angles."
Properties of a Tetradecagon
A tetradecagon has 14 sides, 14 angles, and 28 diagonals. All the interior angles of a tetradecagon add up to 2160 degrees, while each angle measures approximately 154.3 degrees. The sum of the exterior angles of a tetradecagon is 360 degrees, and each exterior angle measures approximately 25.7 degrees.
A tetradecagon can be either regular or irregular. A regular tetradecagon has all its sides and angles equal, while an irregular tetradecagon has sides and angles of different lengths and measures. Regular tetradecagons are often used in geometry problems and constructions due to their symmetry and simplicity.
Real-Life Examples of Tetradecagons
While tetradecagons are not commonly found in everyday life, there are some examples where they can be observed. One example is the shape of a circular fan with 14 blades. Each blade forms an angle of approximately 154.3 degrees with the adjacent blade, creating a tetradecagonal shape when viewed from above.
Another example is the design of some medals or coins that feature a tetradecagonal shape. The Canadian $50 banknote, issued in 2012, has a holographic patch on its front that displays a tetradecagonal shape when viewed at certain angles.
Mathematical Applications of Tetradecagons
Tetradecagons, like other polygons, have various mathematical applications. They can be used in geometry problems, trigonometry calculations, and even in the design of computer graphics and fonts.
For example, in trigonometry, tetradecagons can be used to calculate the values of sine, cosine, and tangent functions for angles that are multiples of 22.5 degrees. These values can be used in various engineering and science fields, such as robotics, physics, and astronomy.
Conclusion
Knowing the name and properties of a shape with 14 sides can be useful in various ways. Tetradecagons, with their 14 angles and sides, have unique properties that make them interesting in geometry and trigonometry. While not commonly found in everyday life, they can be observed in some objects and designs, from circular fans to banknotes. Understanding the names and properties of different shapes can help us appreciate the beauty and complexity of the world around us.
So, the next time you encounter a shape with 14 sides, you will know that it is called a tetradecagon.
