    No, what i am given is that r is perpendicular to s and t is perpendicular to s. I'm trying to prove that r is parallel to t

    oh wait if r and t are perpendicular to the same line then their parallel, Do you know what this theorems called?

    I think it would be something like alternate interior angles theorem

    wait a min, that means all of the angles r 90 degrees...

    If two coplanar lines are perpendicular to a third line, then they are parallel to each other

    If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel.
