"Magnification and reduction of graphics" Transformation and position determination of graphics PPT courseware 3

These three sets of pictures are all the same shape but different sizes.

like this:

The shape is the same, but the figure becomes larger, which is called the enlargement of the figure.

The shape is the same, but the figure becomes smaller, which is called the reduction of the figure.

The picture on the left is long ( ) squares, and the picture on the right is long ( ) squares. The left picture is wide ( ) squares, the right picture is wide ( ) squares

After multiplying the length ( ) of the left image, we get the length of the right image, and after multiplying the width ( ) of the left image, we get the width of the right image.

After multiplying the length ( ) of the right image, we get the length of the left image, and by multiplying the width ( ) of the right image, we get the width of the left image.

To enlarge or reduce a figure, all sides of it must be enlarged or reduced by the same multiple at the same time.
