Explanation:

Step1: Recall vertical angles property

Vertical angles are congruent.

Step2: Check each pair

• For \(\angle1\) and \(\angle3\): They are vertical angles.
• For \(\angle10\) and \(\angle1\): Not vertical angles.
• For \(\angle10\) and \(\angle4\): Not vertical angles.
• For \(\angle11\) and \(\angle1\): Not vertical angles.

Answer:

\(\angle1\) and \(\angle3\)
