Consecutive Exterior Angles : Unlock the Secrets for Perfect Geometry!

Consecutive exterior angles are a pair of angles formed by a transversal and two parallel lines. Consecutive exterior angles are supplementary, meaning their measures add up to 180 degrees.

When two parallel lines are intersected by a transversal, such as a third line that cuts through them, eight angles are formed. These angles can be classified into pairs based on their locations and relationships. Consecutive exterior angles are pairs of angles located outside the parallel lines and on opposite sides of the transversal.

The measure of one angle and the adjacent angle will always add up to 180 degrees. This property holds true for any pair of consecutive exterior angles formed by parallel lines and a transversal. Understanding consecutive exterior angles can be helpful in various geometrical calculations and proofs.
