Question

How do I get L1 and L2 from a Corresponding angles?

Answer 1

Corresponding angles are at the different intersections but on the same side of each parallel line and the same side of the transversal line, like L1 and L4 and L3 and L2. And these angles are equal, so:

L1=L4

L2=L3

So L1=46.2 ° and L2=133.8 °
