NCERT Maths Solutions Class 8 – Chapter 16 Visualizing Shapes – Prism – Part ii Class 8 Maths :- In the previous article, we have discussed the multi-dimensional Visualizing Shapes. Now we will discuss Shapes – Prism. A polyhedron whose side faces are parallelogram and bases are congruent parallel polygons is called a prism. Terms associated with a prism. Base :-The end on which a prism is supposed to stand is called the base of the prism. Every prism has two bases. Height : – The perpendicular distance between the ends of the prism is called the height of the prism. Axis : – The straight line joining the centres of the base of a prism is called the axis of the prism. Length : – The portion of the axis that lies between the parallel ends is called the length of the prism. Lateral Face : – All faces other than the bases of the prism are called the lateral face of the prism. Lateral Edges : – The lines of the interaction of the lateral faces of the prism are called the lateral edges of the prism. The various types of the prism are :-
Right Prism: – If the lateral edges of a prism are perpendicular to its bases a prism is called a right prism. On the other scenario, it is called an oblique. Right prism have i. Length=height ii. All the lateral faces are rectangular iii. All the lateral edges are equal to the height of the prism iv. A number of lateral edges=number of lateral faces=number of sides in the base.
