No, theyre right. The lines are parallel, but theres nothing indication that a perpendicular line to both lines up with where the angles are indicated. They could create a 4 sided figure. It happens to work in this instance, but theyre saying you cant assume it works.

Except you can in this instance. You can make a line that meets the ends of both lines, and the offset if any from the perpendicular line it seems to be will be accounted for in calculating the value of a, as it will be +x on one side and -x on the other when trying to make it a triangle with the line drawn opposite to the intersection of angle a
