Question

price that if a line is perpendicular to one of the two parallel lines then it is perpendicular to the other line also​

Answer 1

Answer:

let's prove it..

Given: A line is perpendicular to A line let AB

To Prove: Line is also perpendicular to other line let CD

proof: A line is perpendicular to line AB

therefore,it makes an angle of 90° with AB

Line AB and CD are parallel...therefore there corresponding angles are equal..

so line makes angle with CD is also 90°..(AB||CD)

therefore the line is perpendicular to CD

.....Hence proved...
