Octahedron.
dimensional proportion
It is a 3 dimensional shaped object
A two-dimensional object is an object that can be drawn on a flat sheet of paper. It's called "two-dimensional" because it has 2 dimensions . . . length and width, but no height.
A polygon is a plane (2-dimensional) object bounded by straight lines. A polyhedron (not polyhendron!) is a solid (3-dimensional) object bounded by polygonal faces. So, pyramids and some prisms are polyhedra. A cylinder is a type of prism but, because two of its faces are circular, those faces are not polygons. As a result a cylinder is not a polyhedron.
when a two dimensional object is transformed by either translation,rotation,scaling,shearing etc on a plane ,it is called two dimensional transformation..
Some triangular pyramids fit this description. They are called regular tetrahedrons.
A pentagon is a 2 dimensional object. The 3 dimensional object, with 12 pentagonal faces, is called a dodecahedron.
A two-dimensional shape that can be folded into a three-dimensional figure is often called a net.

Two dimensional object is a plane figure where as three dimensional object is solid (space) figure.
This is called the volume of the object, the enclosed three-dimensional space.
when a two dimensional object is transformed by either translation,rotation,scaling,shearing etc on a plane ,it is called two dimensional transformation..
A rotation is a movement of an object in a circular motion. A two-dimensional object rotates around a center (or point) of rotation. A three-dimensional object rotates around a line called an axis.
