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

If two parallel lines are cut by a trasnversal then number of pairs of corresponding angles will be :

If two parallel lines are intersected by a transversal then how many pairs of corresponding angles are formed?

If two lines are intersected by a transversal, then how many pairs of interior angles are formed?

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

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

If two parallel lines are cut by a transversal then corresponding angles are equal.
