The obtuse angle is the smaller angle. An angle is more than 45°. 1.5 Complementary and Supplementary Angles 1. answer choices . Angles are usually measured in degrees and denoted by \({\circ}\) (the degree symbol), which is a measure of circularity or rotation.. Angles are a part of our day to day life. It is denoted using the symbol \({\angle}\). An angle is indicated with a curved line. Answer. Central angle is an angle whose vertex is located at the center of the circle and whose sides are radii. Complementary angles are those two angles whose sum is 90 degree. Obtuse Angle. The angle measure ranges from 90° to 180°. So if two angles are complementary, then they are acute (ie less than 90 degrees). Notice that the two angles for a right angle when together. Therefore, there is no complement. Question 71.
