Similar Circles Part 1

Similar Circles Part 1: 1. Consider Circles A and B with radii AD and BC, respectively. 2. Translate one of the circles so that they share a common center (centers overlap). What appears to be true about the circles if we were to compare their sizes? 3. Next, dilate one of the circles by selecting a point on the circle and dragging it, so that they are the same size. What do you think we have shown by performing these transformations? 4. Go to Part 2 of this investigation to explore the relationships between circles further using some measurements.
