Understanding the properties and significance of pentagons in mathematics and the real world

Pentagon

A pentagon is a polygon with five sides and five angles

A pentagon is a polygon with five sides and five angles. The name “pentagon” is derived from the Greek words “penta” meaning 5, and “gonia” meaning angle. Each side of a pentagon intersects with two other sides, and the sum of the internal angles of a pentagon is always 540 degrees. The interior angles of a regular pentagon, where all sides and angles are equal, are each 108 degrees. A regular pentagon has five lines of symmetry and rotational symmetry of order 5, meaning it can be rotated by 72 degrees repeatedly and still look the same. Pentagons can be found in various real-life objects, such as buildings, road signs, and even in nature, like the shape of some leaves.
