As you changed the scale factor of the dilation and the vertices of the triangle, what relationships did you observe between the points, segments and angle measures of the original and the imagine created through a dilation?
For a dilation with a scale factor of k, the rule for changing each point is
Scale Factor Observations
Observations about the effects of the scale factor
Return to the sketch above as needed for the following three questions: When the scale factor is greater than 1, how does the image compare to the original?
When the scale factor is 0<k<1, how does the image compare to the original?
When the scale factor is less than 0, how does the image compare to the original?
What is the scale factor used to dilate BCDE to B'C'D'E'?
Can you do it on your own?
What transformation rules were needed to create the above image?
