If two lines which are parallel are intersected by a transversal then the pair of corresponding angles are equal. From Fig. 3: ∠1=∠6, ∠4=∠8, ∠2= ∠5 and ∠3= ∠7. The converse of this axiom is also true according to which if a pair of corresponding angles are equal then the given lines are parallel to each other.AboutTranscript. Parallel lines are lines in the same plane that go in the same direction and never intersect. When a third line, called a transversal, crosses these parallel lines, it creates angles. Some angles are equal, like vertical angles (opposite angles) and corresponding angles (same position at each intersection).
