Master how to find the complement and supplement of an angle

The video tutorial explains how to determine the complement and supplement of an angle. It covers the definitions of complement and supplement angles, which are pairs of angles that add up to 90 degrees (or π/2 radians) and 180 degrees (or π radians), respectively. The tutorial provides examples of calculating these angles in both degrees and radians, highlighting the importance of using equivalent forms in radians. It also addresses scenarios where no complement exists due to negative results.

What is the sum of two angles that are considered complementary?

• 45 degrees

• 90 degrees

• 180 degrees

• 360 degrees

If angle A is 20 degrees, what is its supplementary angle?

• 110 degrees

• 140 degrees

• 160 degrees

• 70 degrees

What is the complement of an angle measuring 150 degrees?

• 30 degrees

• 60 degrees

• No complement exists

• 90 degrees

In radians, what is the equivalent of 90 degrees?

• 2pi

• pi/2

• pi

• pi/4

What is the supplement of pi/4 in radians?

• pi

• 3pi/4

• pi/2

• pi/3

Why can't a negative angle be a complement?

• Negative angles are not valid complements

• Negative angles are not defined in geometry

• Angles must be positive to exist

• Negative angles are not real

What is the approximate value of pi minus 2?

• 1.31

• 1.41

• 1.54

• 1.14
