Question

I have a quick question. If the angles both have 48 degrees on both lines would you consider that parallel? I'm not sure because there is also 90 degrees and when you add 48+48+90 it equal 186.

Answer 1

We have

the angles in red the measure are 90°

the angles in blue the measure are 90-48=42°

the angles in green the measure are 180°

the lines l1 and l2 are parallels
