Question

two lines are respectively perpendicular to two parallel lines. then these lines to each other
​

Answer 1

Answer:

Now ∠1 and ∠4 are corresponding angles formed by the lines 'p' and 'q'  taking 'm' as transversal and both are equal (each 90°).

This shows that the lines 'p' and 'q'  are parallel to each other.Hence it is proved that if two lines are perpendicular to two parallel lines, then they are parallel to each other.

Answer 2

Answer:

Now ∠1 and ∠4 are corresponding angles formed by the lines 'p' and 'q' taking 'm' as transversal and both are equal (each 90°). ... Hence it is proved that if two lines are perpendicular to two parallel lines, then they are parallel to each other.
