they form a straight line
they are called supplementary angles. a straight line has 180 degrees each side and two adjacent angles forming 180 degrees are called supplementary angles.
A supplementary angle is the angle which produces a straight line of 180° when added to the given angle. To find the supplementary angle, subtract 84° from 180°. The answer will be 96°.
A horizontal line is a line that is parallel to the horizon.
No, because the sum of the 3 angles of a triangle always equals 180 degrees. If two angles are supplementary by definition the two together already sum to 180 degrees, leaving no "space" for the third angle.
Supplementary angles add up to 180 degrees
Supplementary or additional.
supplementary angles form a straight line since they add to 180 degrees by definition
2 angles that add up to 180 degrees are supplementary
no, supplementary angles add to 180, and that definition has nothing to do with how parallel they are.
If they are supplementary to each other then they add up to 180 degrees
NO, by definition only 2 angles can be supplementary. It goes the same way with complimentary
Definition of a supplementary angle: an angle that is supplementary to another angle is an angle in which the sum of both angles forms a straight line or 180 degrees.Definition of a right angle: an angle whose measure is 90 degrees.Using these terms, let's put them into an equation.Right angle + Supplementary angle = 180.90 + Supplementary angle = 180.Subtract 90 from both sides.Supplementary angle = 180 - 90Supplementary angle = 90 degrees.Alternatively, you can think that two right angles are equivalent to a straight line and that all right angles are congruent and therefore; their supplementary angles are also congruent.

Supplementary angles add up to 180 degrees on a straight line
Not necessarily. A linear pair of angles must be supplementary but supplementary angles need not form a linear pair. For example, the opposite angles of a cyclic quadrilateral are supplementary but they are (by definition) not next to one another.
