Question

(B) Prove that two straight lines perpendicular to the same
line are parallel to each other.

Answer 1

Answer:

two straight lines perpendicular to the same

line are parallel to each because perpendicular lines are always straight line intersect to its base not the another perpendicular lines

hope it helps

Answer 2

Answer:

Hey! The answer is:

If a transversal cuts two lines and if the sum of the corresponding angles are equal, then,the two given lines are parallel to each other.

In the given case,

Both the lines are perpendicular to the transversal. So, the corresponding angles are equal to 90 degrees.

Hence,both the given lines are parallel to each other.

I hope this clears your doubts:)
