Description

"Side expansion view of a right prism" PPT courseware 2

learning target:

1. Know the relevant elements and structural characteristics of prisms.

2. Know how to represent prisms.

3. Know that the side view of a prism is a rectangle.

4. Ability to use side expansion diagrams to solve simple problems.

Classification of prisms

Depending on the number of sides of the polygon at the base of the prism, the base of the prism can be a triangle, quadrilateral, pentagon,...

Such prisms are called three prisms, four prisms, five prisms, etc.

Each face of a prism is a polygon and a prism is a polyhedron

Classification of prisms

According to whether the side edge is perpendicular to the bottom surface, it can be divided into:

(1) A prism whose side edges are not perpendicular to the base is called an oblique prism.

(2) A prism with side edges perpendicular to the base is called a right prism.

How to represent a prism

Prisms are usually represented by letters representing the vertices of the base.

Prism ABCD- A1B1C1D1

Related elements and structural characteristics of prisms.

Bottom surfaces parallel and congruent

side rectangle

Side edges parallel and equal

Number of sides (edges) = Number of sides on the bottom
