SOLIDS AND RECTANGULAR PARALLELEPIPEDS

ingress TO SOLIDS
A solid is a limited portion of space bounded by surfaces or plane figures. Polyhedron (plural = polyhedra) is a solid which is bounded by polygons conjugate at their edges. Regular polyhedra or platonic solids ar those whose faces ar all identical regular polygons.

INTRODUCTION TO SOLIDS
Polyhedra are classified according to the number of their faces.

move of a Solid:
Edges are the inter segmentations of the bounding planes. Examples are: AB, BF, AD, DG, GH A Vertices are intersections of the edges. Examples are: A, B, C, D, E, F, G, H B 2

Parts of a Solid:
Lateral Edges are the posture edges which exclude the edges forming the bases. Examples are: A AD, EG, FH, BC Diagonals are line of reasoning segments joining any two vertices not in the said(prenominal) face.
