Question

show that two lines in a plan which a a perpendicular cooler to the same line are parallel to one another​

Answer 1

Answer:

It is given that two lines are respectively perpendicular to two parallel lines, therefore the one line is perpendicular to the other line, hence, they make a right angle with them.  

Now, using the corresponding angle theorem , it proves that these lines are also parallel to each other.  

Hence proved.
