Practice problem
Identifying Intersections and Parallel Lines
Try this following drawing exercise: On a piece of paper, pick a random place and draw a dot. From this dot, extend a line in any direction you like. Now, draw a second dot outside this line. Make a second line that passes through the new dot.
How many ways are there to draw this new line such that, if we were to extend both ends of the two lines infinitely, the two lines would never meet?
