4. given: ∠n ≅ ∠s, line ℓ bisects at q.
prove: ∆nqt ≅ ∆sqr

which reason justifies step 2 in the proof?

if two lines are parallel, then the same-side interior angles formed are congruent.

if two lines are parallel, then the corresponding angles formed are congruent.

vertical angles are congruent.

if two lines are parallel, then the alternate interior angles formed are congruent.

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
