Questions & Step-by-Step Solutions
If angle A and angle B are alternate exterior angles formed by two parallel lines and a transversal, and angle A measures 45 degrees, what is the measure of angle B?
Step 1: Identify that angle A and angle B are alternate exterior angles formed by two parallel lines and a transversal.
Step 2: Recall the property of alternate exterior angles: they are equal when the lines are parallel.
Step 3: Since angle A measures 45 degrees, we can conclude that angle B also measures 45 degrees.
Step 4: Therefore, the measure of angle B is 45 degrees.
Alternate Exterior Angles – When two parallel lines are cut by a transversal, the pairs of alternate exterior angles are equal.
