GEOMETRY Transversal Lines NAME_________________________ DATE __________ Per.___________ Transversals Vocabulary: “transversal” t “exterior” 1 l 2 3 4 “interior” 5 p 6 7 8 “exterior” and ∠5, ∠2 and ∠6 are Corresponding Angles. 1. ∠1 a) Which angle corresponds to ∠3? b) Name another pair of corresponding angles. c) What is a good definition for “corresponding angles”? and ∠6 are Alternate Interior Angles. 2. ∠3 a) Which angle is alternate interior to ∠4? b) What is a good definition for “alternate interior angles”? and ∠5 are Same-Side Interior Angles. 4. ∠3 a) Which angle is same-side interior to ∠4? b) What is a good definition for “same-side interior angles”? and ∠8 are Alternate Exterior Angles. 3. ∠1 a) Name another pair of alternate exterior ∠‘s: b) What is a good definition for “alternate exterior angles”? and ∠8 are Same-Side Exterior Angles. 5. ∠2 a) Name another pair of same-side exterior ∠‘s: b) What is a good definition for “same-side exterior angles”? “Corresponding Angles Postulate” If a transversal cuts two parallel lines, then corresponding angles are congruent. ⇒
