All lines that are parallel to  $\overleftarrow{B}\overrightarrow{H}$

Decide whether pairs of angles ∠1 and ∠2​, ∠6 and ∠1​, and ∠5 and ∠6 are alternate interior​ angles, same-side interior​ angles, corresponding​ angles, or alternate exterior angles.

This diagram of airport runway intersections shows two parallel runways. A taxiway crosses both runways. Which angles are congruent to ∠7? Explain.

A ramp forms the angles shown. What are the values of a and​ b?
