Description
"Zooming in and out of graphics" PPT
Part One: Problem Exploration
Have you seen these phenomena on the left? Which of these phenomena are magnifications of objects? Which ones shrink objects?
What does the length of the two images have to do with each other? How about width?
The length of the first picture is 1/2 the length of the second picture, and the width of the first picture is also 1/2 the width of the second picture.
The length of the second picture is twice the length of the first picture, and the width of the second picture is also twice the width of the first picture.
Magnification and reduction of graphics PPT, part 2: give it a try
Try it: draw a triangle and enlarge it to 3 times the original size, and draw the enlarged figure.
Measure it. Is the length of the hypotenuse of the triangle also 3 times its original length?
The length of the hypotenuse of the triangle is also 3 times the original length.
Observe, what are the similarities between the enlarged graphics and the original graphics? What's different?
The shape of the enlarged graph is the same as the original graph, but the size has changed.
