TRANSVERSAL LINE

__Transversal –__

**
A
transversal is a straight line that intersects two or more lines in a plane. In
the figure the transversal EF intersects the two lines AB & CD at the
points P & Q respectively.**

**The angles formed at the point
P are ∠APE, ∠BPE, ∠APQ and ∠BPQ. The angles formed at the point Q are ∠CQP, ∠DQP,
∠CQF and ∠DQF.**

**These angles, labeled 1 to 8
for convenience, are called –**

**Exterior Angles - ∠4, ∠3, ∠5, and ∠6**

**Interior Angles - ∠1,
∠2, ∠8, and ∠7**

**Alternate
Angles – The pairs ∠1, ∠7 and ∠2, ∠8**

**Corresponding Angles – The pairs ∠1, ∠5; ∠2, ∠6; ∠3, ∠7; and ∠4, ∠8**

**Co-interior Angles – The pairs ∠1, ∠8 and ∠2, ∠7**
