Question

in the cube shown below, which lines are intersecting?
\overleftrightarrow{kl} and \overleftrightarrow{lp} \quad \overleftrightarrow{lm} and \overleftrightarrow{op} \quad \overleftrightarrow{pq} and \overleftrightarrow{mn} \quad \overleftrightarrow{qr} and \overleftrightarrow{lm}

Explanation:

Step1: Define intersecting lines

Intersecting lines share exactly one common point.

Step2: Analyze each pair

• KL & LP: Share point L → intersecting.
• LM & OP: Parallel (no common point).
• PQ & MN: Parallel (no common point).
• QR & LM: Skew (no common point, not parallel).

Answer:

KL and LP
