l and t are parallel to each other

Work Step by Step

If any two lines are perpendicular to the same line, then the two lines are in parallel. For instance, line l is perpendicular to m, meaning l intersects m at a 90 degree angle, and line t is perpendicular to m, meaning t intersects m at a 90 degree angle as well. Because both lines intersect m at the same angle, they are parallel.
