What are complementary and supplementary angles

The video tutorial explains complementary and supplementary angles, starting with the definitions of right and straight angles. It covers how complementary angles add up to 90 degrees and supplementary angles add up to 180 degrees. The tutorial also discusses the conversion of these angles into radians for trigonometry, with 90 degrees equating to pi/2 and 180 degrees to pi. Equations are provided to find complementary and supplementary angles, and limitations are discussed, such as when angles exceed 90 or 180 degrees, making it impossible to find complementary or supplementary angles.

What is the sum of two complementary angles?

• 360 degrees

• 270 degrees

• 180 degrees

• 90 degrees

Which of the following is the radian equivalent of 180 degrees?

• pi

• 3pi/2

• pi/2

• 2pi

If an angle measures 60 degrees, what is its complementary angle?

• 90 degrees

• 150 degrees

• 30 degrees

• 120 degrees

What happens if an angle is greater than 180 degrees?

• It is a right angle

• It has neither a complementary nor a supplementary angle

• It has a complementary angle

• It has a supplementary angle

Why are negative angles not considered in the definition of complementary and supplementary angles?

• They do not fit the definition of adding up to 90 or 180 degrees

• They are only used in trigonometry

• They are too complex to calculate

• They are not used in geometry
