Vertical angles are pairs of angles that are opposite each other when two lines intersect. In this case, since angle \( ∠1 \) measures \( 98^\circ \), the vertical angle would be the one that is opposite to it.
Given the angles:
- \( m∠1 = 98^\circ \)
- \( m∠2 = 82^\circ \)
- \( m∠3 = 98^\circ \)
- \( m∠4 = 82^\circ \)
The angle that shares the same measure as \( ∠1 \) and is directly opposite is \( ∠3 \).
Therefore, the angle that is a vertical pair with \( ∠1 \) is:
\( ∠3 \).
