Question

in the triangular pyramid shown below, which lines are intersecting? select all that apply.
options:
\\(\overleftrightarrow{nq}\\) and \\(\overleftrightarrow{op}\\)
\\(\overleftrightarrow{pq}\\) and \\(\overleftrightarrow{np}\\)
\\(\overleftrightarrow{oq}\\) and \\(\overleftrightarrow{pq}\\)
\\(\overleftrightarrow{pq}\\) and \\(\overleftrightarrow{nq}\\)

Explanation:

Intersecting lines share a common point. In the triangular pyramid, $\overline{PQ}$ and $\overline{MP}$ meet at point $P$; $\overline{OQ}$ and $\overline{PQ}$ meet at point $Q$. These pairs intersect. $\overline{MO}$ and $\overline{OQ}$ are parts of the same edge (connected at $O$), but likely a typo in notation—assuming standard pyramid edges, the clearly intersecting pairs are those with shared vertices.

Answer:

$\overline{PQ}$ and $\overline{MP}$, $\overline{OQ}$ and $\overline{PQ}$
