prove parallel lines
I had to prove two parallel lines on the same plane meet at infinity. No reference any documents. Do not know how to prove this true, or can overlap with other materials. Hope to have comments from you. Email: MicroTri@Gmail.com



On the same plane, there are two parallel lines a and b. C straight line perpendicular to a cut at the point o. Straight line passing y b o cut line at x. Y straight line rotates in the direction of the arrow until it coincides with a straight line.

- When he nearly identical to a (nearly perpendicular y c), point x goes to infinity, but of b.

- When y coincides with a (y perpendicular to c), and point at infinity x belongs a

-> So moving from point x to a, b.

+ There are two cases occurred when x shifts from b to a (when y coincides with a) 1. a meet at infinity b 2. x passing distance between a and b at infinity (y coincides with a right before passing distance between a and b, then y parallel to a, b at infinity), he still cut a in in.

=> In the same plane, two parallel lines meet at infinity.
