Question

in the cube shown below, which lines are intersecting? pt and uv, tu and op, or and rv, qr and tu

Explanation:

Step1: Recall intersecting lines definition

Intersecting lines share a common point.

Step2: Analyze each option

• For $\overrightarrow{PT}$ and $\overrightarrow{UV}$, they are skew - no common point.
• For $\overrightarrow{TU}$ and $\overrightarrow{OP}$, they are skew - no common point.
• For $\overrightarrow{OR}$ and $\overrightarrow{RV}$, they meet at point $R$.
• For $\overrightarrow{QR}$ and $\overrightarrow{TU}$, they are skew - no common point.

Answer:

$\overrightarrow{OR}$ and $\overrightarrow{RV}$
