Yes, you are right. A line segment eventually ends. In fact, a segment has two endpoints. But parallel lines go on forever; they have no endpoints.
Example: <--------------------------->
<---------------------------> (arrows indicating they go on forever)
_______
______________ (these are parallel line segments)
ff
The lines have to intersect because lines go on forever and if then are not parallel then they will collide. Even if they are not parallel by one degree they will still intersect.
No, But 1 Dimensional Does. The lines may or may not go on forever but that has no effect on whether or not a parallel line will cross.
Yes, in plane geometry parallel lines continue forever. However, in polar geometry (3 dimensions, as in Earth longitudinal lines), parallel lines eventually intersect at the poles of the sphere,
parallel
PARALLEL AND PERPENDICULAR LINESParallel lines can run side by side on forever but perpendicular lines make a 90 degree angle.
The lines have to intersect because lines go on forever and if then are not parallel then they will collide. Even if they are not parallel by one degree they will still intersect.
yes two lines that are the same line are parallel because they continue forever and do not intercept.
No, But 1 Dimensional Does. The lines may or may not go on forever but that has no effect on whether or not a parallel line will cross.
Parallel lines are at least two lines that never cross and run forever.
Yes, in plane geometry parallel lines continue forever. However, in polar geometry (3 dimensions, as in Earth longitudinal lines), parallel lines eventually intersect at the poles of the sphere,
parallel side are side that keep going and never touch and two side which carry on forever
Infinite; you could go into the decimal forever.
yes, even if they go on forever they can be.
If two lines go on forever without touching but are not parallel, they are skew, lines that do not lie in the same plane.
Parallel sides are sides that keep going and never touch.Remember, the BASES are the parallel sides.Parallel sides are two lines which carry on forever at the same distance forever, and never, ever touch. Go to this website for more info:http://en.wikipedia.org/wiki/Parallel_(geometry)
parallel
Technically isn't it perpendicular? If it isn't parallel, then they will eventually touch because lines go on forever and if you were to extend it, they'd touch.
