When the sum of two angles is \({90^\circ}\), the angles are called complementary angles. 9.8 b. Answer. An angle is a straight angle if it equals \(180°\). In Euclidean geometry, the two acute angles in a right triangle are complementary, because the sum of internal angles of a triangle is 180 degrees, and the right angle itself accounts for 90 degrees. A right angle equals 90°, so the remaining two angles of a right triangle are complementary, meaning their sum is 90°. (iii) Two angles forming a linear pair are _____.
