Description

"Axisymmetric Graphics" Translation, Rotation and Symmetry of Graphics PPT Courseware 2

teaching objectives

1. Knowledge goal: To enable everyone to further understand the axial symmetry of graphics.

2. Ability goal: Explore the characteristics and properties of axial symmetry in graphs.

3. Emotional goal: Let everyone appreciate the beauty created by graphic transformation during the above activities.

The meaning of axial symmetry:

1. If a figure is folded in half along a straight line, the parts on both sides of the straight line can completely overlap. This figure is called an axially symmetrical figure, and the straight line where the crease is located is its axis of symmetry.

Characteristics of axially symmetrical figures:

The distances between corresponding points and corresponding line segments of an axially symmetric figure and the axis of symmetry are equal.

How to judge the symmetry axis graph

1. Intuitively judge based on the graphic meaning of the symmetry axis.

2. Use the folding method to judge.

Summary of this lesson

The basic starting point of the design of this course is to put everyone as the center, and based on everyone's existing knowledge and experience, actively explore and discover the relationship between the symmetry axis and the symmetry point, and abstract mathematical methods.
