Description

"Re-Understanding of Axial Symmetry (1)" Axial Symmetry and Translation PPT

Part One: Classroom Introduction

1. Go through the process of exploration and further understand the characteristics of axisymmetric graphics.

2. Will determine whether a figure is an axially symmetrical figure.

3. Be able to find the axis of symmetry of an axially symmetrical figure by folding and drawing during the operation.

Re-understanding of axial symmetry PPT, part 2: exploration of new knowledge

Do you recognize these shapes? What are the shapes we have learned? Please take out these figures in your hand, fold them, and then talk about which ones are axisymmetric figures.

Think about how to judge whether a figure is axially symmetrical, and talk to each other in the group. Then the whole class communicates.

think

They all have one thing in common, do you know what it is?

They are all axially symmetric figures.

How to judge whether a figure is axially symmetrical?

After folding a figure in half, if the two sides can completely overlap, then the figure is an axially symmetrical figure.

Re-understanding PPT about axial symmetry, part 3: Class summary

If a figure is folded in half along a straight line and the figures on both sides of the straight line can completely overlap, the figure is an axially symmetrical figure.

What are the characteristics of axisymmetric graphics?

1. The figures on both sides of the symmetry axis completely overlap

2. The distance from the symmetry point to the symmetry axis is equal

Re-understanding of axial symmetry PPT, Part 4: Classwork

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

2. Draw the axis of symmetry of the figure below

3. Practical activities

The two people at the same table were also naughty and smiling, guessing and drawing.

Design competition:

Students design an axially symmetrical figure on the prepared graph paper and draw its axis of symmetry.

Compare your works in the group to see who has the most beautiful and creative design.
