how many side does heptagon have
TopGeometrically, a heptagon is a type of a Polygon which is comprised of seven sides and seven angles. Sides or arms of heptagon are also known as line segments. All sides and angles of heptagon are similar. Sometimes heptagon is also called as septagon. Sides of the heptagon form an angle of 128.6Â° that is edges of heptagon meet to form an angle of 128.6Â°. Here we will discuss how many sides does a heptagon have? Let the side of heptagon be 'l'. Interior angle and exterior angles of heptagon are 128.571Â° and 51.43Â° respectively. The number of diagonals and Triangles in a heptagon are 14 and 5 respectively. Number of triangles are composed by lining the diagonals from a given vertex. Addition of interior angles in a heptagon is equals to 900Â°. Diagonals are calculated as 7. (7 - 3) / 2 = 14.
