## Pasch's TheoremEdit

If A, B, C are distinct noncollinear points and *l* is any line intersecting AB in a point between A and B, then *l* also intersectseither AC or BC. If C does not lie on *l*, then *l* does not intersect both AC and BC

### ExplanationEdit

## Crossbar TheoremEdit

If ray AD (need LaTex formatting) is between ray AC(need LaTex formatting) and ray AB(need LaTex formatting), then ray AD(need LaTex formatting) intersects segment BC
