Question

in the triangular prism shown below, which lines are intersecting?

Explanation:

Step1: Recall intersecting - lines definition

Intersecting lines share a common point.

Step2: Analyze each option

• For $\overleftrightarrow{PR}$ and $\overleftrightarrow{MN}$, they are skew lines (not in the same plane and do not intersect).
• For $\overleftrightarrow{MO}$ and $\overleftrightarrow{NQ}$, they are skew lines.
• For $\overleftrightarrow{MO}$ and $\overleftrightarrow{NO}$, they intersect at point $O$.
• For $\overleftrightarrow{PR}$ and $\overleftrightarrow{MO}$, they are skew lines.

Answer:

$\overleftrightarrow{MO}$ and $\overleftrightarrow{NO}$
