# Chapter 3 - Parallel and Perpendicular Lines - Chapter Test - Page 211: 6

$m\angle 1$ is $85^{\circ}$, and $m\angle 2$ is $95^{\circ}$.

#### Work Step by Step

If the lines are parallel, then $m\angle 1$ is $85^{\circ}$ because the angle whose measurement is given and $\angle 1$ are corresponding angles, which are congruent. $\angle 1$ is supplementary to $\angle 2$ because they are same-side interior angles, which are supplementary. Let's subtract $m\angle 1$ from $180^{\circ}$ to find $m\angle 2$: $180 - 85 = 95$ $m\angle 1$ is $85^{\circ}$, and $m\angle 2$ is $95^{\circ}$.
