Using complementary angles to find the missing value

The video tutorial explains how to determine the measures of angles formed by intersecting lines. It highlights that if one angle is a right angle, all angles are 90 degrees, indicating perpendicular lines. The tutorial then guides viewers on solving for unknown angles by setting up equations, emphasizing the importance of assigning variables and solving systematically.

What can be inferred if one angle formed by intersecting lines is a right angle?

• All angles are obtuse.

• All angles are complementary.

• All angles are acute.

• All angles are right angles.

What is the first step in solving for an unknown angle when given certain angle measures?

• Set up an equation.

• Use a protractor.

• Draw a diagram.

• Guess the angle measure.

If the measure of angle 4 is 32 degrees, what equation can be set up to find the measure of angle 5?

• Measure of angle 4 * measure of angle 5 = 90 degrees

• Measure of angle 4 + measure of angle 5 = 90 degrees

• Measure of angle 4 - measure of angle 5 = 90 degrees

• Measure of angle 4 + measure of angle 5 = 180 degrees

What is the measure of angle 5 if angle 4 measures 32 degrees?

• 68 degrees

• 62 degrees

• 60 degrees

• 58 degrees

What is the final step in solving for an unknown angle using an equation?

• Multiply the known angle by 2.

• Subtract the known angle from 90 degrees.

• Add the known angle to 90 degrees.

• Divide the known angle by 2.
