you can coordinate parallel because parallel lines never touch or cross
Corresponding angle are used to prove if lines are parallel. If they are congruent then the lines cut by the transferal are parallel.
By stating they are parallel.
The term that best describes a proof in which you assume the opposite of what you want to prove is 'indirect proof'.

A coordinate proof
Yes. You can use this to prove that two lines are parallel, in analytic geometry, i.e., geometry that uses coordinates.Yes.

Quite possibly, but it will depend on the lines!
By stating they are parallel.
now you can see that two parallel lines are intersected by another two ll lines therefore we can prove congurent in two traingle by constructing a line in quadiletral formed therefore their angle are equal nd are prallel
If the lines have the same slope but with different y intercepts then they are parallel
Yes, they do. Parallel Lines do meet at Infinity. Right, how to prove it. Experiment to prove : Take a comb ( obviously the lines should be parallel). take it to a dark room and apply light to it from a torch. You can see that at some poin in the wall The lines do meet. This proves my theory. This idea is also proposed by my guru Mr. Maria Das.
Pretty much the only thing you need to know to determine if two lines are parallel is the gradient of those lines. Simply put, are the lines on the same plane?
Postulates are assumed to be true and we need not prove them. They provide the starting point for the proof of a theorem. A theorem is a proposition that can be deduced from postulates. We make a series of logical arguments using these postulates to prove a theorem. For example, visualize two angles, two parallel lines and a single slanted line through the parallel lines. Angle one, on the top, above the first parallel line is an obtuse angle. Angle two below the second parallel line is acute. These two angles are called Exterior angles. They are proved and is therefore a theorem.
Two lines are parallel if they never cross one another. Another way to tell if they are parallel is if they have the same slope. Also, if the same line intersects both of them at a 90 degree angle, they would be parallel (in other words, if both lines are perpendicular to a common line, they are paraellel).
You can prove it if you can prove that one pair of opposite sides is parallel (and, strictly speaking, that the other pair is not). Proving that the lines are parallel depends on the information available. Thier equations may have the same slope (gradient), or that the angles at their ends are supplementary, etc.
