## FAQs on Complementary Angles Video Lecture - Quantitative Aptitude for SSC CGL

 1. What are complementary angles?
Ans. Complementary angles are a pair of angles whose sum is equal to 90 degrees. In other words, when two angles are complementary, they add up to form a right angle.
 2. How can I determine if two angles are complementary?
Ans. To determine if two angles are complementary, you need to add their measures. If the sum is equal to 90 degrees, then the angles are complementary. If the sum is greater or less than 90 degrees, then they are not complementary.
 3. Can complementary angles be acute angles?
Ans. No, complementary angles cannot be acute angles. Acute angles are angles that measure less than 90 degrees. Complementary angles, on the other hand, must have a sum of precisely 90 degrees, which means one angle must be acute and the other must be obtuse.
 4. Is it possible for two obtuse angles to be complementary?
Ans. No, two obtuse angles cannot be complementary. Obtuse angles are angles that measure greater than 90 degrees. Since complementary angles must have a sum of exactly 90 degrees, one angle must be acute, and the other must be obtuse.
 5. How can complementary angles be used in real-life situations?
Ans. Complementary angles can be used in various real-life situations, such as measuring the angles of a triangle or determining the angle of elevation or depression. They are also utilized in construction, engineering, and architecture to ensure precise angles and measurements.
