Unit 6 Visualising Solid Shapes(final)
3D shapes/objects are those which do not lie completely in aplane. 3D objects have different views from different positions. A Solid is a polyhedron if it is made up of only polygonal faces, thefaces meet at edges which are line segments and the edges meet ata point called vertex. Euler s formula for any polyhedron is,F + V E = 2 Where F stands for number of faces, V for number of vertices andE for number of edges. Types of polyhedrons:(a)Convex polyhedronA convex polyhedron is one in which all faces make it (1)(2)(3)(4)12/04/18 (1) and (2) are convex polyhedrons whereas(3) and (4) are non convex polyhedron.
