A triangle? Three lines that intersect in three points.
a transversal
It's possible, but for any three lines in the same plane, there could be ether one point of intersection (unlikely) or three (more probably).
No, skew lines are not perpendicular. Perpendicular lines intersect at an angle of ninety degrees, while skew lines never intersect (think in three dimensions or higher).
In geometry, three or more lines are said to be concurrent if they intersect at a single point.
