Description

"Simple Axisymmetric Figures" Axisymmetric PPT Courseware

Self-study tips:

1. Read it (pages 100~101 of the book)

2. Do it (experiments in the book)

3. Think about it (what have you discovered through experiments?)

True or False:

1. The aircraft diagram is not necessarily an axially symmetrical figure. ( )

2. There are countless axes of symmetry in a semicircle. ( )

Multiple choice questions:

1. ★There are ( ) axes of symmetry. A. 5 B. 10 C. 1

2. The Chinese character ( ) below is an axially symmetrical figure. A. word B. small C. day

True or False:

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

2. A square has only two axes of symmetry. ( )

Multiple choice questions:

1. A rectangle has ( ) axes of symmetry. A. 1 B. 2 C. 3

2. The figure below ( ) is an axis-symmetric figure. A. 3 B. 9 C. 7

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

The line along which the crease is located is called the axis of symmetry.

Axisymmetric graphics:

Squares, rectangles, isosceles triangles, isosceles trapezoids and circles are all axially symmetric figures. Some axially symmetric figures have more than one axis of symmetry.

"Simple Axisymmetric Figures" Axisymmetric PPT Courseware 3 Scenario Question 1 Without using tools, please divide an angle made of paper into two equal angles. What can you do? Situation Question 2: For this kind of foldable angle, we can use the angle bisector of the folding method. For...

"Simple Axisymmetric Figures" Axisymmetric PPT Courseware 2:

"Simple Axisymmetric Figures" Axisymmetric PPT Courseware 2 Do it (1) Draw an angle AOB on a piece of paper, cut along both sides of the angle and fold the angle in half so that the two sides of the angle overlap. (2) Pick any point C on the crease (i.e. the angle bisector); (3) Fold O through point C..
