"Magnification and reduction of graphics" Transformation and position determination of graphics PPT courseware

Show it off and talk about it.

1. Work together at the same table and use matchsticks to place two squares of different sizes.

And talk about the characteristics of these two graphics?

Can you lay out two squares of different sizes?

Both figures have the same shape. From left to right, the graphic shrinks.

From left to right, the graphic enlarges, but its shape remains unchanged.

Practice and application

1. Talk about the changes between the two graphs below.

2. Use a small stick to form a triangle so that its side length is 1/2 of the side length in the picture below.

3． On graph paper, reduce each side of the picture below to 1/2 of its original size.

4. On the graph paper, enlarge the diameter of the two circles to twice the original size.
