Vertical angles cannot, by definition, be adjacent (next to each other). For #3, did you write that vertical angles will be complementary only when they each measure 45°? Only when vertical angles, a, are 45 ° can they be complementary.

Another property of vertical angles is that angles that are next to each other are supplementary angles, meaning that they add up to 180 degrees. credit-by-exam regardless of age or education level. Vertical angles are angles that are opposite each other when two lines intersect each other. Enrolling in a course lets you earn progress by passing quizzes and exams. Supplementary angles add to 180°, and only one configuration of intersecting lines will yield supplementary, vertical angles; when the intersecting lines are perpendicular. These two angles can be located anywhere. Put a vertical line on the right of the letter 'c' in 'complementary' to make into … 100. Here we say that the two angles complement each other.
