Parallel segments two segments are parallel if the corresponding lines determined by them are parallel.

Parallel rays two rays are parallel if the corresponding lines determined by them are parallel.In other words two rays in the same plane are parallel if they do not intersect each other even if extended indefinitely beyond their initial points.

Parallel lines

Parallel lines___

A transversal intersects two parallel lines. Prove that the bisectors of any pair of corresponding angles so formed are parallel.

Rewrite each of the following statements in the form 'p if and only if q'. Give below are pairs of statements. Combine them using 'if and only if' : p : If two lines are parallel, then their slopes are equal. q : If the slopes of two lines are equal, then they are parallel.

If a transversal intersects two parallel lines, then corresponding angles are on the ______ side of the transversal

If two lines are parallel, then what can you say about the pairs of corresponding angles formed by their transversal ?

If a transversal intersects two lines such that the bisectors of a pair of corresponding angles are parallel,then prove that the two lines are parallel.
