Explanation:

Step1: Identify angle relationship

First, find the supplementary angle of $107^\circ$ on line $a$:
$180^\circ - 107^\circ = 73^\circ$

Step2: Compare with angle on line $b$

The corresponding angle on line $b$ is $73^\circ$. For parallel lines cut by a transversal, corresponding angles must be equal. Here, the calculated corresponding angle matches the given angle on line $b$.

Answer:

Lines Parallel?: yes
Reason: Corresponding angles are equal
