Question

in the cube shown below, which lines are intersecting? eh and gh cd and gh cg and eh ef and dh

Explanation:

Step1: Recall intersecting - line definition

Intersecting lines meet at a point.

Step2: Analyze each option

• For $\overline{EH}$ and $\overline{GH}$, they meet at point $H$.
• $\overline{CD}$ and $\overline{GH}$ are skew lines (not in the same plane and do not intersect).
• $\overline{CG}$ and $\overline{EH}$ are skew lines.
• $\overline{EF}$ and $\overline{DH}$ are skew lines.

Answer:

$\overline{EH}$ and $\overline{GH}$
