Question

identifying relationships think of each segment in the diagram as part of a line. there may be more than one right answer. 15. name a line perpendicular to $overleftrightarrow{qr}$.

Explanation:

Step1: Recall perpendicular - line definition

Two lines are perpendicular if they intersect at a right - angle.

Step2: Analyze the rectangular prism

In the given rectangular prism, if we consider line $\overleftrightarrow{QR}$, lines like $\overleftrightarrow{QX}$, $\overleftrightarrow{UR}$, $\overleftrightarrow{TW}$ are perpendicular to it as they intersect $\overleftrightarrow{QR}$ at right - angles. Let's choose $\overleftrightarrow{QX}$.

Answer:

$\overleftrightarrow{QX}$
