Question

in the square pyramid shown below, which lines are intersecting? select all that apply.
options:
\\(\overleftrightarrow{jm}\\) and \\(\overleftrightarrow{mn}\\)
\\(\overleftrightarrow{kl}\\) and \\(\overleftrightarrow{lm}\\)
\\(\overleftrightarrow{lm}\\) and \\(\overleftrightarrow{mn}\\)
\\(\overleftrightarrow{kn}\\) and \\(\overleftrightarrow{mn}\\)

Explanation:

Intersecting lines share a common point. $\overline{KL}$ and $\overline{LM}$ share point L; $\overline{LM}$ and $\overline{MN}$ share point M; $\overline{KM}$ and $\overline{MN}$ share point M. $\overline{JM}$ and $\overline{MW}$ are not shown as intersecting (no common labeled point).

Answer:

$\overline{KL}$ and $\overline{LM}$, $\overline{LM}$ and $\overline{MN}$, $\overline{KM}$ and $\overline{MN}$
