Vertical angles are formed by two intersecting lines and are the angles that are opposite each other. In this case, the angles that share a vertex (in this particular arrangement) are related to each other.
Given the angles:
- m∠1 = 98°
- m∠2 = 82°
- m∠3 = 98°
- m∠4 = 82°
The vertical angle pairs would be:
- ∠1 and ∠3 are vertical angles because both are 98° and are opposite each other.
- ∠2 and ∠4 are also vertical angles because both are 82° and are opposite each other.
Thus, the angle that is a vertical pair with ∠1 is ∠3.
