Question

Write the conditions under which two lines are parallel.​

Answer 1

Answer:

the pair of corresponding angles is equal, then the two straight lines are parallel to each other. the pair of alternate angles is equal, then the two straight lines are parallel to each other. the pair of interior angles on the same side of transversal is supplementary, then the two straight lines are parallel.

Answer 2

Answer:

If the two lines are parallel, the angle between them and the positive side of x-axis will be equal. The figure given below illustrates the above situation. (v) Condition for the lines to be parallel in terms of the perpendicular distance between them.
