IMPORTANT: The angles are named vertex-point on leg-point on leg.

Angles are vertical if they share a vertex.

$\angle ABC$, $\angle ACD$, $\angle ADE$ and $\angle AEC$ are vertical.

Angles are vertically opposite if they are also opposite from each other.

$\angle ABC$ and $\angle ADE$ are vertically opposite, as are $\angle ACD$ and $\angle AEC$.

Similarly, asymptotes can be vertical, horizontal or slanted.

So, if angles can be vertical, can they be horizontal or slanted?

  • $\begingroup$ Here "vertical" does not mean up-and-down. No... there is no analogous use of the terms "horizontal" and "slanted." $\endgroup$ – David G. Stork Apr 4 at 18:27
  • $\begingroup$ no, but they can be complementary, supplementary, linear pair. They can also be right or cute (acute angle). $\endgroup$ – Vasya Apr 4 at 18:28
  • $\begingroup$ @DavidG.Stork : I know that "vertical" does not mean up or down. $\endgroup$ – 1gr8penguin Apr 4 at 18:29
  • $\begingroup$ Oh! And also, they should be ANSWERS, not COMMENTS! $\endgroup$ – 1gr8penguin Apr 10 at 16:14
