How to classify angles given by intersecting lines?

Below you can see a graph with two intersecting lines where 4 angles are formed.

There are two pairs of angles.

  • Adjacent angles, such that their sum is equal to 180°.
  • Non-adjacent angles (also called vertical angles).

In the image:

  • 1-2
  • 2-3
