Two angles whose measures have a sum of 90 degrees. Angles /_a and /_b are complimentary (sum of them equals to 90^o) and acute. Acute angle are those measured less than 90o . Complementary angles do not need to be adjacent angles or oriented in the same direction. A right angle equals 90°, so the remaining two angles of a right triangle are complementary, meaning their sum is 90°. degree. In a right angled triangle, the two non-right angles are complementary, because in a triangle the three angles add to 180°, and 90° has already been taken by the right angle. An angle is a straight angle if it equals \(180°\). However, vertical angles are not adjacent: $\alpha$ and $\beta$ are not vertical angles, they are a linear pair.
