    Ok so basically what I need to do is find the radius of the circles and square it but that's all I have so far I think

    Well circle B lies on (-1,-9) and (-1,-1).....circle D lies on (7,2) and (7,6).... now to see if they are the same you must subtract the y1 by y2 on both circles....

    aren't all circles similar? i keep seeing this question but it never makes any sense to me they are similar because they are circles

    I proved it a while back that all circles are similar but I think another easy way mentioned by a friend of mine was showing that the ratio to the circumference to the diameter is pi, therefore making the circles similar :P

    coolio I figured it out. I just have to dilate the circles by 2. thanks y'all.

    Yup! That's good, dilation and transformations are the common ways to showing it :)!
