<p>Hmm, I miss these sometimes. They're random type questions asking..</p>
<p>If three circles/lines/etc are drawn in a plane, what is the maximum number of points of intersection? Are there any rules for stuff like this?</p>
<p>Your best bet is to draw out as many possibilities as you can, and go from there. You shouldn’t rely on any “rule.”</p>
<p>Yeah, those are really annoying at times, and if you’re not looking at it properly, it could mess you up. Just draw all the possibilities and eliminate answers that are too low.</p>
<p>It’s best to just be old-fashioned and count them.</p>
<p>Thanks for the advice.</p>
