Question

which angles are vertical to each other? ∠2 and ∠3 ∠4 and ∠6 ∠3 and ∠1 ∠3 and ∠6

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and have equal measures.

Step2: Analyze each option

• For $\angle2$ and $\angle3$, they are adjacent angles, not vertical angles.
• For $\angle4$ and $\angle6$, they are vertical angles as they are opposite each other at the intersection of two lines.
• For $\angle3$ and $\angle1$, they are not vertical angles.
• For $\angle3$ and $\angle6$, they are not vertical angles.

Answer:

$\angle4$ and $\angle6$
