Questions & Step-by-Step Solutions
If two parallel lines are intersected by a transversal and one of the exterior angles is 120 degrees, what is the measure of the corresponding interior angle?
Step 1: Understand that when two parallel lines are cut by a transversal, several angles are formed.
Step 2: Identify the exterior angle given in the question, which is 120 degrees.
Step 3: Recall that the corresponding interior angle is supplementary to the exterior angle. This means they add up to 180 degrees.
Step 4: To find the corresponding interior angle, subtract the exterior angle from 180 degrees: 180 - 120.
