Question

in the square pyramid shown below, which lines are intersecting? select all that apply. (overrightarrow{mn}) and (overrightarrow{no}) (overrightarrow{kl}) and (overrightarrow{ko}) (overrightarrow{ko}) and (overrightarrow{lo}) (overrightarrow{ko}) and (overrightarrow{mo})

Explanation:

Step1: Recall intersecting lines definition

Intersecting lines meet at a point.

Step2: Analyze $\overleftrightarrow{MN}$ and $\overleftrightarrow{NO}$

They meet at point $N$, so they are intersecting.

Step3: Analyze $\overleftrightarrow{KL}$ and $\overleftrightarrow{KO}$

They meet at point $K$, so they are intersecting.

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

They meet at point $O$, so they are intersecting.

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

They meet at point $O$, so they are intersecting.

Answer:

$\overleftrightarrow{MN}$ and $\overleftrightarrow{NO}$, $\overleftrightarrow{KL}$ and $\overleftrightarrow{KO}$, $\overleftrightarrow{KO}$ and $\overleftrightarrow{LO}$, $\overleftrightarrow{KO}$ and $\overleftrightarrow{MO}$
