I think it has something to do with triangles, but I can't quite find the relation.

I know this is probably really confusing, but I tried drawing a picture of it on paint and when I went to post it, it said I cn't post websites; please help me, I really don't get it.

**Reiny**, Thursday, October 25, 2007 at 10:44pmIf a quadrilateral inside a circle has its 4 vertices on the same circle, then it is a cyclic quadrilateral.

One of the properties is that opposite angles add up to 180º

I think this is the relationship you are looking for according to your description.
