Decagon

A decagon is a polygon, a two-dimensional shape with straight sides. Specifically, a decagon is a polygon with exactly ten sides and ten angles. It can be regular, meaning all sides and angles are equal, or irregular, where sides and angles can vary. The sum of the interior angles of any decagon is always 1440 degrees. The word 'decagon' derives from the Greek words 'deka' (ten) and 'gonia' (angle or corner). Its properties are extensively studied in geometry and are crucial in understanding the characteristics of other polygons. The area of a regular decagon can be calculated using various formulas involving its side length or apothem (the distance from the center to the midpoint of a side).

Decagon meaning with examples

• The architect's blueprint featured a decagon-shaped building, designed to maximize natural light from multiple angles. Its unique form stood out from the more common square or rectangular structures, making it a landmark in the city. The complex engineering calculations ensured the structural stability and aesthetic appeal of the unusual, ten-sided design.
• During their geometry lesson, the students learned how to calculate the perimeter of a regular decagon, given that each side measured 15 centimeters. The teacher explained the formulas and demonstrated how to find the area, emphasizing the importance of precise measurement and consistent units to the problem.
• The artist created a mosaic using tiles arranged to form a large, irregular decagon on the gallery floor. The design, with its ten sides and varied angles, created a visually captivating piece, exploring the concept of fragmentation and wholeness, inviting viewers to see patterns.
• The city planners proposed a decagon-shaped park to create a central gathering space within the neighborhood. The design allows for multiple entrances and pathways leading to the park's center, creating diverse and engaging experiences for people from all walks of life.
• The construction crew used specialized machinery to cut out the ten equal sides of the decagon-shaped base for the new water tower. Accuracy was paramount, as any deviation would compromise the structural integrity of the tower. This attention to the shape proved to be essential for the overall longevity of the water system.
