Let's take the same figure - line l and m are parallel.
And line p is the transversal.
Exterior angles are angles which are
outside lines l & m
So, ∠1, ∠2, ∠7, ∠8 are exterior angles
Angles made by the transversal - Theory
Parallel Lines
Transversal
Angles made by the transversal
Interior angles
Alternate Interior Angles
Exterior angles (when transversal intersects two parallel lines) You are here
Alternate exterior angles
Proof of Alternate Exterior Angle Equal
Interior angles on same side of transversal
Corresponding Angles
