Introductionm23bf061465e100fa_1528450127855_0Introduction

The solids presented below:

[Illustration 1]

are called prisms.

The following figure shows the elements of the prism.

[Illustration 2]

The student can answer the question:

- How many bases, vertices and edges does this prism have?

Procedurem23bf061465e100fa_1528446435040_0Procedure

Task
Watch and answer the questions:

What is the shape of the lateral faces of presented prisms?

What does the name of the prism depend on?

[Interactive illustration]

The definition
The right prism is a spatial figure with:
- two bases of identical polygons,
- lateral faces of rectangles.m23bf061465e100fa_1527752263647_0The right prism is a spatial figure with:
- two bases of identical polygons,
- lateral faces of rectangles.

The name of the prism depends on the shape of its polygonal basebasebase.

Task
Name the prisms shown in the figure. Give the number of:

a) lateral edges,

b) basebasebase edges,

c) lateral faces,

d) vertices

of each of these prisms.

[Illustration 3]

Task
According to the figure calculate:

a) the sum of the edges length of the prism,

b) the basebasebase area of the prism,

c) the perimeter of the lateral facefaceface of the prism.

[Illustration 4]

Notice that the bases of the prism are parallel to each other, and the lateral edges are perpendicular to the base edges.
The lateral faces are also perpendicular to the bases of the prism.m23bf061465e100fa_1527752256679_0Notice that the bases of the prism are parallel to each other, and the lateral edges are perpendicular to the base edges.
The lateral faces are also perpendicular to the bases of the prism.

Lesson summarym23bf061465e100fa_1528450119332_0Lesson summary

The right prism is the spatial figure with two bases of identical polygons and lateral faces of rectangles.
The name of the prism depends on the shape of its polygonal base for example the pentagonal prism has a base of pentagon.m23bf061465e100fa_1527712094602_0The right prism is the spatial figure with two bases of identical polygons and lateral faces of rectangles.
