Show that triangle ABC is similar to triangle PQR by translating triangle ABC so that point B coincides with point Q. Find the scale factor that you need to use to dilate triangle A^ prime B^ prime C^ prime so that its image triangle A^ prime prime B^ prime prime C^ prime prime coincides with triangle PQR . What was the ordered pair rule you used? What technique could you use to find the center of dilation? You will explore more about finding the center of dilation in the performance task at the end of this lesson.
