Q1
Lines $\ell$ and $m$ are explicitly marked parallel. A transversal intersects them, forming angles labeled $\angle 1$ through $\angle 8$ in the standard way: at the top intersection, $\angle 1$ is upper-left, $\angle 2$ is upper-right, $\angle 3$ is lower-left, $\angle 4$ is lower-right; at the bottom intersection, $\angle 5$ is upper-left, $\angle 6$ is upper-right, $\angle 7$ is lower-left, $\angle 8$ is lower-right. Which angle pair can be proven congruent?
