Eight line segments with the same length, the internal angle of each line segment is 135, and the plane figure of closed shape formed by end-to-end connection is called octagon. Every corner of a regular octagon is equal in size and every side is equal in length. Every corner of a regular octagon is equal in size and every side is equal in length. The sum of the internal angles of a regular octagon is 1080 degrees, each internal angle is 135 degrees and each external angle is 45 degrees.

Octagon is a kind of figure in mathematics, which is a closed figure surrounded by eight line segments connected end to end. It has eight sides and eight corners. Octagonal can be divided into regular octagon and non-regular octagon. The sum of the inner angles of an octagon is 1080 degrees, and the sum of the outer angles is 360 degrees.
The circumference is equal to the sum of the lengths of eight sides. Eight line segments with the same length, the internal angle of each line segment is 135, and the plane figure of closed shape formed by end-to-end connection is called octagon. An octagon that is not a regular octagon is called an irregular octagon.
