Question

in the cube shown below, which lines are intersecting? cf and cg ei and gh fj and gh fj and dh

Explanation:

Step1: Recall intersecting - lines definition

Intersecting lines meet at a point.

Step2: Analyze each option

• For $\overleftrightarrow{CF}$ and $\overleftrightarrow{CG}$, they meet at point $C$.
• For $\overleftrightarrow{EI}$ and $\overleftrightarrow{GH}$, they are parallel and do not intersect.
• For $\overleftrightarrow{FJ}$ and $\overleftrightarrow{GH}$, they are skew - lines and do not intersect.
• For $\overleftrightarrow{FJ}$ and $\overleftrightarrow{DH}$, they are skew - lines and do not intersect.

Answer:

$\overleftrightarrow{CF}$ and $\overleftrightarrow{CG}$
