learning target

Preliminarily understand axisymmetric figures, understand the characteristics of axisymmetric figures, and be able to accurately determine which objects in life are axisymmetric figures. (emphasis)

You can manually cut out axially symmetrical figures and find the symmetry axis of axially symmetrical figures. (difficulty)

Scenario import

There is a lot of mathematical knowledge in these amusement projects. Today we will study the movement of graphics together.

Explore new knowledge

Knowledge points: Understand symmetry phenomena and axisymmetric figures

The shapes cut out like this are all symmetrical, they are all axially symmetrical shapes

The straight line where the crease in the middle of the figure is located is the axis of symmetry of the figure.

Knowledge refining

After folding in half along a certain straight line, the two sides of the figure can completely overlap. Such a figure is called an axially symmetric figure, and the straight line is called the axis of symmetry.

Consolidation exercises

1. (Selected from textbook P33 T2) Which of the following digital patterns are axially symmetrical?

2. (Selected from textbook P33 T3) From which folded paper were the following figures cut? One after another.

Class summary

After folding in half along a certain straight line, the two sides of the figure can completely overlap. Such a figure is called an axially symmetric figure, and the straight line is called the axis of symmetry.
