mathmale · Answer

I'd appreciate YOUR input. 

In Question 1 (if I'm reading it correctly), we're supposed to show that the two circles are similar.  In my understanding, ALL circles are similar.  Much depends upon what "similar" means in geometry.

What do YOU think?  Could you explain what we're looking for here in your own words?

anonymous · Answer

I understand that the two circles will be similar because all are since their dimensions are proportional.

mathmale · Answer

Yes.  each one has its own radius, and the radius of a circle never changes.  so, at first glance, it appears that two concentric circles meet the criteria for similarity.

Lady K:  So sorry, but I need to get off the 'Net, having been on for four-five hours this morning already.  Hope we can work together again soon!!
