Question

in the square pyramid shown below, which lines are intersecting? select all that apply.

Explanation:

Step1: Understand intersecting lines

Intersecting lines are lines that meet at a point.

Step2: Analyze each pair

• For $\overleftrightarrow{BE}$ and $\overleftrightarrow{CE}$: They meet at point $E$.
• For $\overleftrightarrow{CE}$ and $\overleftrightarrow{DE}$: They meet at point $E$.
• For $\overleftrightarrow{AE}$ and $\overleftrightarrow{DE}$: They meet at point $E$.
• For $\overleftrightarrow{AB}$ and $\overleftrightarrow{AE}$: They meet at point $A$.

Answer:

All the given pairs ($\overleftrightarrow{BE}$ and $\overleftrightarrow{CE}$, $\overleftrightarrow{CE}$ and $\overleftrightarrow{DE}$, $\overleftrightarrow{AE}$ and $\overleftrightarrow{DE}$, $\overleftrightarrow{AB}$ and $\overleftrightarrow{AE}$) are intersecting lines.
