Five outstanding facts about octagons fact number one. An octagon has eight sides. It is a 2d shape. The Octagon gets its name from OCTA which means eight and gone which means sides there are 20 diagonals in an octagon as you can see. But number two there are regular octagons and irregular octagons in a regular octagon, all sides and angles are equal. Each angle of a regular octagon is 135 degrees. fact number three in an irregular octagon all sides and all angles are not equal. Measure of angles of an irregular octagon or different but they all sum up to 1080 degrees.
but number four a convex octagon has no angles pointing inwards. More precisely. No internal angles can be more than 180 degrees. When any internal angle is greater than 180 degrees it is concave. Think concave has a cave in it, but number five. The perimeter of a polygon is the total length of its boundary in order to calculate the perimeter of an octagon the length of all the sides must be known. We know that in a regular octagon all of the side or people length. Therefore the formula that is used to find its perimeter is equal to the sum of all its sides perimeter of a regular octagon equals 8 a Where a is the length of one side of the octagon? See you soon.
