## NCERT Solutions Class for 8 Maths Visualizing Shapes Prism

** 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.

**Triangular prism: –**If the base of a prism is triangles, a prism is called a triangular prism. A triangular prism has

i. 6 vertices and 9 edges

ii. 2 triangular bases

iii. 3 rectangular lateral faces

**Right Triangular prism: – A triangular prism whose lateral edges are perpendicular to its bases is called a right triangular prism**

The prism is further classified on the basis of the number of sides in the bases.

** Rectangular prism :-** It is also called cuboid or rectangular solid. It has 6 rectangular faces along with 8 vertices and 12 edges.

** Pentagonal prism : – **A pentagonal prism has 2 pentagons as bases along with 5 rectangular lateral faces, 10 vertices, and 15 edges.

** Hexagonal prism : – **If the numbers of sides in the base of the prism are six, it is known as a hexagonal prism.

** Parallelepiped : –** If the bases of a quadrilateral prism are parallelograms it is called a parallelepiped
