Question

if two lines are perpendicular to the same line, then they are ______ to each other. a) complementary b) perpendicular c) parallel d) congruent

Explanation:

In the context of lines in a plane, if two lines are both perpendicular to the same line, by the properties of parallel lines (specifically, the theorem about lines perpendicular to a transversal), these two lines are parallel to each other. Complementary refers to angles, perpendicular would mean they intersect at 90 degrees (but two lines perpendicular to the same line don't intersect at 90 degrees with each other), and congruent is for figures with equal size/shape, not lines' relationship here.

Answer:

C) parallel
