Today Let's learn octagon shape. In geometry Octagon shape is a polygon which has eight sides and eight angles.

A regular octagon has sides of same length and each interior angles also measures same. You can also get help from geometry word problems. Some basic properties of octagon shape are:

• We can draw 20 diagonals in regular octagon shape.
• Each internal angles measures 135⁰.
• We can divide a regular octagon into 6 triangles.
• Sum of all internal angles of a regular octagon is 1080⁰.
• Each external angles measures 45⁰.

Perimeter of an octagon is calculated using perimeter formula: means adding length of all sides of an regular octagon: P = 8a

This is all about properties of octagon. Also you can gain better learning online on math as well as other topics such as English Rhymes help and so on.
