Question

in the square pyramid shown below, which lines are intersecting? select all that apply.
kl and ko km and lo lo and mn ko and lo

Explanation:

Step1: Recall intersecting lines definition

Intersecting lines share a common point.

Step2: Analyze $\overleftrightarrow{KL}$ and $\overleftrightarrow{KO}$

They share point K, so they intersect.

Step3: Analyze $\overleftrightarrow{KM}$ and $\overleftrightarrow{LO}$

They are skew - no common point, so they don't intersect.

Step4: Analyze $\overleftrightarrow{LO}$ and $\overleftrightarrow{MN}$

They are skew - no common point, so they don't intersect.

Step5: Analyze $\overleftrightarrow{KO}$ and $\overleftrightarrow{LO}$

They share point O, so they intersect.

Answer:

$\overleftrightarrow{KL}$ and $\overleftrightarrow{KO}$, $\overleftrightarrow{KO}$ and $\overleftrightarrow{LO}$
