These angles always come in pairs, so one angle is the. If two congruent angles form a linear pair, the angles are right angles. Supplementary angle In geometry, an angle is the figure formed by two rays or line segments, called the sides of the angle, sharing a common endpoint. Supplementary angles are pairs of angles such that the sum of their angles is equal to 180 degrees. A linear pair forms a straight angle which contains 180º, so you have 2 angles whose measures add to 180, which means they are supplementary.

If two angles form a linear pair, the angles are supplementary. Supplementary angles have two properties: Only two angles can sum to 180° - three or more angles may sum to 180° or 2 radians, but they are not considered supplementary.


H Vocabulary Word: Radius Definition: A line segment with one endpoint at. After going through the adjacent and non-adjacent complementary angles in complementary angles definition, one can determine what adjacent and non-adjacent supplementary angles will be. Let the measure of one of the supplementary angles be a. Q Vocabulary Word: Supplementary Angles Definition: Two angles whose sum is 180.These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°: Notice that together they make a straight angle Two Angles are Supplementary when they add up to 180 degrees.
