If the two circles' radii are congruent, can the circles still be shown to be similar?
1. No, since they are congruent.
2. No, since there exists no scale factor that will dilate one circle onto the other.
3. Yes, since all congruent shapes are similar (with scale factor 1).
4. Yes, since congruent radii means they have the same area, and any shapes with equal areas are similar.
