Description

"Designing with Axial Symmetry" Axisymmetric PPT in Life

Part One: Learning Objectives

1. Experience the process of pattern design using axial symmetry, further understand axial symmetry and its properties, accumulate experience in mathematical activities, and develop spatial concepts.

2. Understand the widespread application and rich cultural value of axial symmetry in real life.

Using axial symmetry to design PPT, part 2: classic examples

[Example 1] The graphics in the picture below are all axially symmetrical graphics. Please try to draw their axes of symmetry. (Just draw one line for each)

[Example 2] The picture shows a 4×4 square grid, in which 3 small squares have been painted black. Now we need to select one of the remaining 13 small white squares and paint it black to make a pattern composed of black squares. Become an axially symmetrical figure, such a small white square has ()

Using axial symmetry to design PPT, the third part: Variation exercises

1. Use the symmetry points in the figure to draw the symmetry axis of the figure.

2. As shown in Figure ①, it is a 4×4 square grid. Two square squares have been blackened. Please blacken two of the squares again, and make the entire blackened pattern an axially symmetrical figure. As agreed After rotation, congruent patterns are considered to be of the same type. The two pictures in Figure ② are considered to be of the same type, and the different patterns obtained have a total of ()

Using axial symmetry to design PPT, Part 4: Consolidation training

3. Our country issues a set of zodiac stamps every year. Among the following zodiac stamps, the animal’s “head” is designed with an axially symmetrical pattern: ()

4. Fold a rectangular piece of paper in half, then use the tip of a pen to poke a "B" on it, and then lay it flat, you can see ()

5. There are two line segments drawn on the square grid as shown in the picture. Now we need to draw another one so that the three line segments in the picture form an axially symmetrical figure. The line segments that can meet the conditions are ()
