Given two straight lines A and B and a line segment C that intersects both of them forming two interior angles on one side that together are less than 2 right angles (180°/pi) then the lines A and B must eventually meet on that same side and therefor are not parallel.
Given a straight line L and any point P not on L there is a single, unique line through P that is parallel to L.
Welp, I gave it a read and remembered why I didn't enjoy Maths.It's all moonrunes to me.

I'm not great at them by any means. I figure something like this where I have to learn them myself in order to tell who got it right is the best thing I can do.
MFW proofs
I certainly would be in interested in more of these, but geometry is a weak point. We've barely looked over it in my courses. We discussed the fifth postulate last week, but not much else.
Does the answer involve making a line perpendicular to l through p?

I drew a picture but it won't upload to imgur for some reason.SpoilerDraw a line L and a point P away from that line. Draw a line C through P perpendicular to L. Draw another line A perpendicular to C through P. Euclid's Fifth Postulate states that angles in a triangle add to 180 (2 right angles, which we have). The lines L and A are parallel, so they will not meet to form a triangle. Any other line drawn through P would form a triangle, but no other parallels exist.Probably haven't explained well. I'm tired.

Is that it?SpoilerI had a similar thing were you would have to make a triangle such that all the 90+90+x=180, where x is the angle between the lines L and P, and x>0. Obviously, that doesn't exist, hence parallel.I thought it would be much worse than that.
These questions are so oddly simple and complicated at the same time.
