Question

1. which of the following angle pairs form vertical angles in the picture below? (choose all that apply.) <1 and <2 <1 and <3

Explanation:

Step1: Recall the definition of vertical angles

Vertical angles are the pairs of opposite angles formed when two lines intersect.

Step2: Analyze each pair

• For \(\angle1\) and \(\angle2\): They are adjacent angles, not opposite angles.
• For \(\angle1\) and \(\angle3\): They are opposite angles formed by the intersection of two lines.

Answer:

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