Question

in the triangular prism shown below, which lines are intersecting? pr and mn qr and mp pq and mp or and mn

Explanation:

Step1: Recall intersecting lines definition

Intersecting lines meet at a point.

Step2: Analyze each option

• For $\overleftrightarrow{PR}$ and $\overleftrightarrow{MN}$, they are skew - not intersecting.
• For $\overleftrightarrow{QR}$ and $\overleftrightarrow{MP}$, they are skew - not intersecting.
• For $\overleftrightarrow{PQ}$ and $\overleftrightarrow{MP}$, they meet at point $P$, so they are intersecting.
• For $\overleftrightarrow{OR}$ (assuming you mean $\overleftrightarrow{QR}$) and $\overleftrightarrow{MN}$, they are skew - not intersecting.

Answer:

$\overleftrightarrow{PQ}$ and $\overleftrightarrow{MP}$
