Vertical angles are the angles opposite each other when two lines intersect. In this case, since you have four angles that all share a common vertex, we can identify vertical pairs based on their respective measures.
Given:
- m∠1 = 98°
- m∠2 = 82°
- m∠3 = 98°
- m∠4 = 82°
The angles that share a measure with each other are:
- ∠1 (98°) and ∠3 (98°) are a vertical pair.
- ∠2 (82°) and ∠4 (82°) are a vertical pair.
Since you are asking for the angle that is a vertical pair with ∠1, the answer is:
∠3 (98°) is the vertical pair with ∠1.
