Question

If two straight lines are perpendicular to same line then we have to prove that they are parallel to each other.plz help me in this question it is very urgent to me

Answer 1

a transversal cuts two different lines and if the sum of the corresponding angles is equal to 180 degrees

Then,

the two given lines are parallel to each other

and here,

both the lines are perpendicular to the transversal

So,

the sum of angles made by them on the transversal is 180 degrees

Hence,both the given lines are parallel to each other

Answer 2

They are parallel lines as the corresponding angles formed on the two lines are equal.As both measures 90 degree.
Since corresponding angles are equal so lines are ||.
Please mark me as brainliest i needed urgently.
