Definition of Alternate Exterior Angles
Definition of Alternate Exterior Angles
When two lines are crossed by a transversal (a third line that crosses both lines), a number of different pairs of angles are formed.
The angles formed by the transversal and the lines that are on opposite sides of the transversal, but on the outside of the two lines are called alternate exterior angles.
Angles \(a\) and \(b\) in the diagram on the left are alternate exterior angles.
Note: When the two lines crossed by the transversal are parallel, the alternate exterior angles are equal.
Description
