Are vertical angles supplementary angles?
1 Answer
Vertical and supplementary are different relationships between angles.
However, there is a special case when vertical angles are supplementary as well - when these angles are right ones.
Explanation:
Vertical angles are formed by two intersecting lines. On a picture below angles
Supplemental angles are those that, if positioned adjacent to each other, form a straight angle.

In one particular case, when vertical angles are right angles (that is, lines that form this pair of vertical angles are perpendicular), their sum is equal to a straight angles and, therefore, they are supplemental.
See the picture below that represents angles formed by perpendicular lines.
