Question

The answer to the wuestion

Answer 1

Here t is perpendicular to both lines l and m

at line l , it makes an angle 1 which is 90 degrees

at line m , it makes an angle 2 which is 90 degrees

so angle 1 = angle 2 =90 degree

they are also corresponding angles

if corresponding angles are equal then the two lines are parallel to each other.

so line l and m are parallel.
