Question

line wv is perpendicular to both line rs and line tu. which statement must be true about line tu? line tu is parallel to line rs. line tu is perpendicular to line rs. line tu has no slope. line tu has a slope of -5.

Explanation:

If two lines are both perpendicular to a third line, then those two lines are parallel to each other. Here, line \(WV\) is perpendicular to both line \(RS\) and line \(TU\). So, by the property of perpendicular lines in a plane, line \(TU\) and line \(RS\) must be parallel.

Answer:

Line TU is parallel to line RS.
