Intersection of Circles

Subject: Intersection of circles

I have been given a geometry problem, and do not understand the term 
intersection. I have looked in the FAQ section, and cannot find 
anything, and the dictionary states that it is the point where two 
lines meet. Is this correct?

Hi, Stephen,

Yes, that's correct. Draw one circle. Then draw another circle
that overlaps the first one. There will be two places where the 
circles cross; those are the two points of intersection of the 
circles. If the two circles don't overlap, there are no points of 
intersection, and if they just barely touch (we say they are tangent), 
there is only one point.
