state the theorom that you can use to prove that r is parallel to s.

GIVEN: r is perpindicular to t, t is perpindicular to s


plz explain
 
There's not a big immediate visual differrence between "perpendicular" and "parallel". It just looked exactly like your last post.

This one isn't transitive. You may have to resort to alternate interior angles.

What work have you done on these problems? We can't tell.
 
Draw lines that LOOK parallel, s and r.
Draw a line between them that LOOKS perpendicular to both, t.

Make annotations about what perpendicular means and it should pop out at you.
