Write a complete two column proof for the following information.
andrey2020 [161]
We are asked to show a proof that m∠1 is equal to 62° and the line l is parallel to line m which has an angle of 180°. If two lines are parallel the summation of angles are 180 degrees and they are also considered as a supplementary angle. Hence, by this we have formed the equation and solution below:
m∠l + m∠m = 180° 
replacing the value of two angles, we have:
62° + 118° = 180°
180° = 180°

Therefore, the two lines are parallel.
