in the cube shown below, which lines are intersecting?
$ \overleftrightarrow { a e } $ and $ \overleftrightarrow { f g } $
$ \overleftrightarrow { a e } $ and $ \overleftrightarrow { b f } $
$ \overleftrightarrow { a d } $ and $ \overleftrightarrow { e h } $
$ \overleftrightarrow { a b } $ and $ \overleftrightarrow { b c } $

Question

Accepted Answer

# Explanation:
## Step1: Recall the definition of intersecting lines
Intersecting lines are lines that meet at a point.
## Step2: Analyze each pair
- For $\overleftrightarrow{AE}$ and $\overleftrightarrow{FG}$: In a cube, $AE$ and $FG$ are parallel (not intersecting).
- For $\overleftrightarrow{AE}$ and $\overleftrightarrow{BF}$: $AE$ and $BF$ are skew (not in the same plane, not intersecting).
- For $\overleftrightarrow{AD}$ and $\overleftrightarrow{EH}$: $AD$ and $EH$ are skew (not in the same plane, not intersecting).
- For $\overleftrightarrow{AB}$ and $\overleftrightarrow{BC}$: $AB$ and $BC$ meet at point $B$ (intersecting).

# Answer:
$\overleftrightarrow{AB}$ and $\overleftrightarrow{BC}$
