Subject: Re: Similar figures

Another way to attack this problem is to take a simple picture, copied with a
copier, change it size and copy it. Put both the original and several size
changes on a one sheet. This could be a work activity sheet for students to
measure and fill in a table. They could look at the various ratios with the
original and try to guess what was the size change that you made.

With the same activity you could change the position of the size changed
image. For example, rotate the picture 90 degrees or 180 degrees. The
students might not know that the figures are similar until they measure them
and tell you the size change.
