This document contains notes from a math lesson on dilations. It discusses how to accurately dilate circles using enough points and the proper location of points. It also covers how to reverse a dilation by using the reciprocal of the original scale factor. Examples are worked through of dilating triangles and circles and reversing dilations. The homework assignment is to complete problems from pages 19 and 18 in the textbook.

The number of points to dilate that is enough is as
many as are needed to produce a dilated image that
looks like the original. For curved figures, like this
circle, the more points you dilate the better. The
location of the points you choose to dilate is also
important.
