If you mean the capital letter "F" there is 3.
The 3 angle bisectors of a triangle intersect in a point known as the INCENTER.
3 angle
30 150 and 150 (for a total of 360 degrees)
Only in some cases: 1. The angles are supplementary 2. The angles are at a single point on a straight line and all on the same side of it 3. The interior angles of a triangle. and a few more complicated scenarios. Otherwise, the answer is NO.
No, they can intersect at infinitely many points.
No, that is not true.

Assuming that the none of the lines are parallel, they can intersect (pairwise) at three points. Otherwise, the question is tautological.

If you mean: y = 2x+2 and y = 3x-1 then it works out as x = 3 and y = 8 meaning that the point of intersection is at (3, 8) on the coordinated plane.

If you mean the capital letter "F" there is 3.
No, never.
I'm pretty sure it's a vertex
Line #1 ==> Y = x Line #2 ==> Y = x + 1 These two lines are parallel, have no points in common, and never intersect. (3 ways to say the same thing)
