# If angles can be vertical, can they be horizontal or slanted?

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?

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