Identifying Complementary and Supplementary Angles

The video tutorial explains how to identify and match pairs of angles using a diagram. It covers complementary angles, which sum to 90 degrees, vertical angles formed by intersecting lines, and supplementary angles, which sum to 180 degrees. The tutorial provides examples and guides viewers through selecting the correct angle pairs from given options.

What type of angles sum up to 90 degrees?

• Adjacent angles

• Vertical angles

• Supplementary angles

• Complementary angles

Which pair of angles forms a right angle in the diagram?

• Angle 1 and Angle 2

• Angle 3 and Angle 4

• Angle 4 and Angle 5

• Angle 2 and Angle 3

What is the correct pair of complementary angles identified in the video?

• Angle 4 and Angle 5

• Angle 3 and Angle 5

• Angle 1 and Angle 2

• Angle 1 and Angle 3

What are vertical angles?

• Angles next to each other

• Angles that are both acute

• Angles across from each other on intersecting lines

• Angles that add up to 180 degrees

Which pair consists of vertical angles from the diagram?

• Angle 2 and Angle 3

• Angle 3 and Angle 5

• Angle 1 and Angle 2

• Angle 4 and Angle 5

What defines supplementary angles?

• Angles that sum to 180 degrees

• Angles that are vertical

• Angles that are identical

• Angles that sum to 90 degrees

Which pair of angles forms a straight angle in the diagram?

• Angle 3 and Angle 4

• Angle 4 and Angle 5

• Angle 1 and Angle 2

• Angle 2 and Angle 3

Which angles are correctly identified as supplementary in the video?

• Angle 4 and Angle 5

• Angle 2 and Angle 3

• Angle 1 and Angle 2

• Angle 3 and Angle 4

What mistake was initially made when identifying supplementary angles?

• Incorrectly identifying non-intersecting angles

• Choosing angles that do not form a straight line

• Selecting a pair not listed as an option

• Confusing them with complementary angles

How are complementary and supplementary angles different?

• Complementary angles add up to 90 degrees

• Supplementary angles add up to 90 degrees

• Supplementary angles form a right angle

• Complementary angles are larger
