A decagon is a ten-sided polygon, which means it has ten straight edges and ten corners, or vertices. Each angle in a regular decagon, where all sides and angles are equal, measures 144 degrees. Decagons can be found in various shapes and sizes, making them interesting shapes in geometry.
You can see decagons in real life, such as in some stop signs or in the design of certain buildings. They are also used in art and design, where their unique shape can create visually appealing patterns. Understanding decagons helps us appreciate the beauty of geometry in our everyday surroundings.
