Question

in the cube shown below, which lines are intersecting? qr and mq os and mq st and mn qr and op

Explanation:

Step1: Recall definition of intersecting lines

Intersecting lines share a common point.

Step2: Analyze each option

• For $\overrightarrow{QR}$ and $\overrightarrow{MQ}$, they share point $Q$.
• $\overrightarrow{OS}$ and $\overrightarrow{MQ}$ are skew - no common point.
• $\overrightarrow{ST}$ and $\overrightarrow{MN}$ are skew - no common point.
• $\overrightarrow{QR}$ and $\overrightarrow{OP}$ are skew - no common point.

Answer:

$\overrightarrow{QR}$ and $\overrightarrow{MQ}$
