What is a 8 sided 2D shape called?
octagon
An octagon is a closed two-dimensional figure with eight sides, eight vertices and eight interior angles. If all the sides and interior angles of an octagon are of equal measure, then it is called a regular octagon otherwise an irregular octagon.
Is there a 8 sided shape?
A regular octagon shape has eight equal sides and eight equal angles. All the sides are of equal length, and all the angles are of equal measure. The sum of the interior angles is 1080°, and the sum of the exterior angles is 360°. In a regular octagon, the interior angle at each vertex is 135°.

What is the name of 2D shapes?
2D Shapes Names. The basic types of 2d shapes are a circle, triangle, square, rectangle, pentagon, quadrilateral, hexagon, octagon, etc. Apart from the circle, all the shapes are considered as polygons, which have sides. A polygon which has all the sides and angles as equal is called a regular polygon.
