What are complementary angles

The video tutorial explains the concept of complementary angles, which are two angles whose measures add up to 90 degrees. It clarifies the definition of right angles and how they are identified by a box symbol. The tutorial provides examples of complementary angles and discusses the difference between vertical and adjacent angles. It concludes with an example of angles that are not complementary, emphasizing the importance of visual indicators like the box to determine angle measures.

What is the correct definition of complementary angles?

• Angles that sum to 180 degrees

• Angles that sum to 90 degrees

• Angles that are equal

• Angles that are adjacent

How can you identify a right angle in a diagram?

• By a box symbol

• By its size

• By its position

• By its color

What is a key characteristic of vertical angles?

• They are formed by intersecting lines

• They share a common side

• They are always adjacent

• They are always complementary

Which of the following is true about adjacent angles?

• They are formed by intersecting lines

• They are always equal

• They share a common side and vertex

• They do not share a vertex

Why can't you assume two angles are complementary without a box symbol?

• The box symbol indicates they are equal

• The box symbol confirms they sum to 90 degrees

• The box symbol shows they are adjacent

• The box symbol is irrelevant
