# State whether following statement is true or false:A line perpendicular to one of two parallel lines is perpendicular to the other.

True

##### SOLUTION
Assume $m || n , \, m \, \bot \, I$
Ref. image
We know the parallel lines. make equal iterior angles with a transversal line.
So angle made by n with $I$ is $90^{\circ}$.
So $n \, \bot \ I$. You're just one step away
