Are all 8 sides of an octagon equal?

The octagon having eight congruent sides and angles is known as a regular octagon. ... In a regular octagon, all the sides are equal in length, and all the angles are equal in measure. The interior angles add up to 1080° and the exterior angles add up to 360°. The interior angle at each vertex of a regular octagon is 135°.

What is the surface area of a regular octagon?

Area of a Regular Octagon

The most widely used formula to calculate the area of regular octagon is given as: A = 2a2 (1 + √2), where a represents the given octagon's each side length.

How do you find area?

To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

What is the diameter of an octagon?
