Exploring Vertical and Adjacent Angles

The video tutorial explains intersecting lines, focusing on vertical and adjacent angles. It describes how vertical angles are congruent and how adjacent angles can be supplementary, adding up to 180 degrees. The tutorial includes examples to illustrate these concepts, helping students understand angle relationships and calculations.

What are vertical angles?

• Angles that are on the same line

• Angles that are next to each other

• Angles that are directly across from each other

• Angles that add up to 90 degrees

If angle 1 is 130 degrees, what is the measure of its vertical angle?

• 50 degrees

• 100 degrees

• 130 degrees

• 180 degrees

What is the measure of angle 4 if angle 2 is 43 degrees?

• 137 degrees

• 86 degrees

• 180 degrees

• 43 degrees

What does the term 'adjacent' mean in mathematics?

• Angles that share a common side or wall

• Angles that are on the same line

• Angles that add up to 90 degrees

• Angles that are directly across from each other

Which of the following pairs of angles are adjacent?

• Angle 3 and Angle 1

• Angle 1 and Angle 2

• Angle 2 and Angle 4

• Angle 1 and Angle 3

What does it mean for angles to be supplementary?

• They are directly across from each other

• They add up to 180 degrees

• They share a common side

• They add up to 90 degrees

If the measure of angle 4 is 36 degrees, what is the measure of its supplementary angle?

• 180 degrees

• 144 degrees

If angle W is 76 degrees, what is the measure of its vertical angle?

• 90 degrees

• 180 degrees

• 104 degrees

• 76 degrees

If angle X is 104 degrees, what is the measure of its adjacent angle?

• 76 degrees

• 90 degrees

• 104 degrees

• 180 degrees
