"Re-Understanding of Axial Symmetry (2)" Download PPT of Axial Symmetry and Translation

Part One: Exciting Introduction

Naughty drew the whole house (see picture ②) based on half of the axially symmetrical small house (see picture ①). Was he right?

It cannot be completely overlapped after folding.

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

There are 2 spaces from the leftmost point under the house to the axis of symmetry;

There is 1 block from the left side of the small door in the house to the axis of symmetry.

Using the dotted line as the axis of symmetry, draw the other half of the figure on the graph paper.

First imagine the process of folding in half...

First find the endpoints of each line segment, and then find the points that are symmetrical to these points...

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

1. Using the dotted line as the axis of symmetry, draw the symmetry points of each of the following points, and talk about how you drew them.

2. Taking the dotted line as the axis of symmetry, draw the axially symmetrical figure of the following figure.

3. Design an axially symmetrical figure on the graph paper below.

4. Using the dotted line as the axis of symmetry, draw the symmetry points of each of the following points.

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

Draw the other half of the axially symmetrical figure

First find the endpoints of each line segment.

Then find points that are symmetrical to these points

Connect these symmetry points in order
