A solid cannot be bounded by one polygon. A solid bounded by polygons is called a polyhedron.
A regular octagon has 8 sides.
An 8 sided octagon can be either regular or irregular in shape.
A polygon with eight sides, regular or not, is an octagon. There isn't a special name for a regular octagon (other than "regular octagon").
A regular octagon has 8 sides similarly to an octagon. The name regular octagon means that all angles are the same, therefore inferring that all sides are of equal length.
No not just any shape that has 8 side can be called an octagon. An octagon has straight lines that make up a closed bounded shape.
In a regular octagon, each angle is 135 degrees. If the octagon is not regular, then it can have as many as 6 right angles in it.
A octagon is a octagon without the same angles as the others.
An octagon is a plan figure with eight sizes, a regular octagon is an octagon with all the eight sizes being equal to each other
A regular prism.
An octagon can be regular if all the sides are the same length, and all the angles are the same. However an octagon is not necessarily regular.If the interior/exterior angles are a certain size, then it will be regular but if each angle was 95 degrees then the octagon would definitely not be regular!
A regular octagon will not tessellate but an irregular one can.
