Angle Relationships

The video tutorial explains the concept of angles, including their components such as legs and vertex. It covers how to identify angles by their points and vertex, and discusses different types of angle relationships like complementary, supplementary, adjacent, and vertical angles. The tutorial also explains how intersecting lines create various angle relationships and how to calculate unknown angles using these relationships.

What is the point called where the two legs of an angle meet?

• Endpoint

• Vertex

• Intersection

• Arc

How can an angle be identified using its points?

• By listing the vertex last

• By listing the points in any order

• By listing the vertex in the middle

• By listing the vertex first

What is the sum of two complementary angles?

• 360 degrees

• 90 degrees

• 45 degrees

• 180 degrees

What is the sum of two supplementary angles?

• 90 degrees

• 180 degrees

• 45 degrees

• 360 degrees

Which of the following is true about adjacent angles?

• They form a right angle

• They are always equal

• They share a common leg

• They do not share a leg

What is the relationship between vertical angles?

• They are always equal

• They are always adjacent

• They are always supplementary

• They are always complementary

If angle ABC is 122 degrees, what is the measure of its vertical angle?

• 180 degrees

• 122 degrees

• 58 degrees

• 90 degrees
