are vertical angles always complementary

The Lesson: In the triangle shown below, the angles A and B are complementary because they have a sum of 90º. So, you subtract the 80 from the 180 to find that your top angle measures 100 degrees. vertical angles are very specific - you have two have two intersecting lines to form two sets of vertical angles which are across from each other and congruent. Answer: a = 140°, b = 40° and c = 140°. So, picture two lines that intersect each other. Yes, vertical angles are congruent. Try refreshing the page, or contact customer support.

Example: Find angles a°, b° and c° below: Because b° is vertically opposite 40°, it must also be 40° A full circle is 360°, so that leaves 360° − 2×40° = 280° Angles a° and c° are also vertical angles, so must be equal, which means they are 140° each. 147­149 Work with a partner. They do not need to be next to each other. Complementary in mathematics means "adding to 90°," but it also is an adjective generally used to mean "combining in a way that enhances something," like two people with complementary skills--one cooks and one bakes, for instance.
