Review the definitions of the types of angles pairs that can be formed by a transversal.
corresponding angles
To determine what type of relationship the pair of highlighted angles has, we should consider the types of angles pairs that can be formed by a transversal. Let's examine the given angles ∠4 and ∠2.
From the diagram, we can see that the angles ∠4 and ∠2 lie on the same (right) side of the transversal. Moreover, ∠2 is interior, but ∠4 is exterior. They must be corresponding angles.
