Vertical and Complementary Angles

The video tutorial explains how to solve angle problems using diagrams. It covers complementary angles to find the measure of angle 2, vertical angles to determine angle 5, and supplementary angles to calculate angle 4. The tutorial emphasizes understanding the relationships between angles formed by intersecting lines and right angles.

If angle 1 measures 43 degrees and forms a right angle with angle 2, what is the measure of angle 2?

• 47 degrees

• 43 degrees

• 53 degrees

• 90 degrees

What is the sum of the measures of two complementary angles?

• 360 degrees

• 90 degrees

• 180 degrees

• 45 degrees

If angle 3 is 141 degrees, what is the measure of angle 5, given they are vertical angles?

• 39 degrees

• 180 degrees

• 141 degrees

• 90 degrees

Vertical angles are formed by:

• Two parallel lines

• Two intersecting lines

• A right angle

• A straight line

If angle 3 is 141 degrees, what is the measure of angle 4, given they are supplementary?

• 39 degrees

• 141 degrees

• 90 degrees

• 180 degrees

What is the sum of the measures of two supplementary angles?

• 45 degrees

• 180 degrees

• 90 degrees

• 360 degrees

Which of the following pairs of angles are complementary?

• 90 degrees and 90 degrees

• 45 degrees and 45 degrees

• 60 degrees and 120 degrees

• 30 degrees and 60 degrees
