Using Consecutive Angles to Find the Missing Measure of an Angle

The video tutorial explains the concept of interior angles formed by two parallel lines and a transversal. It introduces consecutive interior angles, which are on the same side of the transversal, and explains that their sum is 180 degrees. The tutorial also demonstrates how to solve for unknown angles by subtracting known angle measures.

What are the characteristics of the interior angles formed by two parallel lines and a transversal?

• They are exterior angles.

• They are always equal.

• They are on the same side of the transversal.

• They are on alternating sides of the transversal.

What is another name for consecutive interior angles?

• Alternate interior angles

• Same side interior angles

• Corresponding angles

• Vertical angles

How do consecutive interior angles relate to each other?

• They are supplementary.

• Their sum is 180 degrees.

• Their sum is 90 degrees.

• They are equal.

If one of the consecutive interior angles is 53 degrees, what is the measure of the other angle?

• 180 degrees

• 90 degrees

• 53 degrees

• 127 degrees

What is the first step in solving for an unknown consecutive interior angle?

• Divide the known angle by 2.

• Multiply the known angle by 2.

• Add 53 degrees to the known angle.

• Subtract 53 degrees from 180 degrees.
