Explanation:

Step1: Recall vertical angles definition

Vertical angles are opposite angles formed by two intersecting lines.

Step2: Analyze each option

• $\angle1$ and $\angle2$: Adjacent angles, not vertical.
• $\angle2$ and $\angle3$: Adjacent angles, not vertical.
• $\angle3$ and $\angle4$: Adjacent angles, not vertical.
• $\angle1$ and $\angle3$: Opposite angles formed by two intersecting lines, so they are vertical angles.

Answer:

$\angle1$ and $\angle3$
