SHAPES Definition for shape: A shape is a geometric figure that can be described with mathematics. One way to classify shapes is to describe a bigger shape that the shape fits inside of. For example, two-dimensional shapes like circles will fit inside of a flat plane. Three-dimensional objects like cubes will not fit inside of a plane, because they are not flat.Two shapes are said to be equal, if one can be changed into the other by spinning, moving, growing bigger, shrinking, or more than one of these in a combination

3-D SHAPES

Three dimensional objects or solids generally have length, breadth and height. Three dimensional objects look different from different locations or angles.

THREE-D SHAPS :- cube,cylinder,sphere, cone

A polyhedron is a solid shape bounded by polygons whereas non-polyhedrons do not have polygon shaped faces.

Cubes, cuboids, prisms, and pyramids are few examples of polyhedrons.

Spheres, cones and cylinders are a few examples of non-polyhedrons.

CONVEX POLYHEDRONS:

The column of Vertices + Faces and compare it to Edges. The Vertices + Faces is always two more than Edges. You can write this down as a formula:

V - E + F = 2

vertices-edges+faces=2
