Part One: Exciting Introduction

Fold in half along the dotted line in the middle, then the parts on both sides of the dotted line can completely overlap.

Such a graph is an axially symmetrical graph, and the dotted line in the middle is the axis of symmetry.

Re-understanding PPT about axial symmetry, part 2: knowledge explanation

What are the axially symmetrical figures?

Is Figure 3 an axisymmetric figure?

The size and shape of the figures on the left and right sides are the same, and it is an axially symmetrical figure.

No matter which straight line the figure ③ is folded along, the shapes on both sides cannot completely overlap. It is not an axially symmetrical figure.

A figure that can be completely coincident when folded in half is an axially symmetrical figure. Figure ③ is not an axially symmetrical figure

Re-understanding PPT about axial symmetry, part three: practice and consolidation

1. Please draw the axis of symmetry of the figure below and fill in the blanks.

2. What are axisymmetric figures? Tell us the reasons for your judgment.

3. Draw the axis of symmetry of the figure below.

4. Draw the axes of symmetry of the figure below. How many axes can you draw for each?

Re-understanding of axial symmetry PPT, part 4: knowledge summary

Axisymmetric figures have different numbers of symmetry axes. To determine how many axes of symmetry there are, it depends on how many straight lines the figure can be folded in such that the figures on both sides can completely overlap.
