CCSS What are supplementary and complementary angles

The video tutorial explains the difference between complementary and supplementary angles. Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees. The video provides examples and clarifies that angles do not need to be adjacent to be complementary or supplementary. It also discusses the degree measurement system, emphasizing the significance of 360 degrees in a circle, and how it relates to 180 and 90 degrees.

What is the sum of two complementary angles?

• 90 degrees

• 180 degrees

• 360 degrees

• 45 degrees

Which of the following statements is true about supplementary angles?

• They can be non-adjacent and still add up to 180 degrees.

• They are always equal.

• They add up to 90 degrees.

• They must always be adjacent.

How can you represent a 90-degree angle in a diagram?

• With a straight line

• With a circle

• With a box

• With a triangle

If angle E is 60 degrees and angle F is 30 degrees, what type of angles are they?

• Supplementary

• Complementary

• Equal

• Adjacent

Which of the following is NOT a characteristic of complementary angles?

• They can be represented with a box for 90 degrees.

• They must be adjacent.

• They can be non-adjacent.

• They add up to 90 degrees.
