Title Notes 3.1 Lines and Angles
10/8/13

3. Transversals
A transversal is a line that intersects two coplanar lines at two different points.
Transversal b, intersects lines a and c. m l
Transversal m, intersects lines l and k. b k a c

4. Special Angles Pairs formed by a Transversal2 1 3
Interior Angles are formed inside lines r & s:
∠3, ∠4, ∠5 𝑎𝑛𝑑 ∠6 4 r 5 6 s 8 7
Exterior Angles are formed outside lines r & s:
∠1, ∠2, ∠7 𝑎𝑛𝑑 ∠8
Corresponding Angles:
∠1 & ∠5
, ∠6 & ∠2,
∠4 & ∠____
8 ,
∠7 & ∠3
Consecutive (Same Side) Angles:
Angle pairs that lie in the same relative position on both intersections 3
∠4 & ∠5
,∠6 & ∠____
Alternate Interior Angles:
∠4 & ∠6
, ∠5 & ∠_____ 3
Interior angle pairs that lie on the same side of the transversal.
Alternate Exterior Angles:
Interior angle pairs that lie on opposite sides of the transversal.
, ∠2 & ∠_____ 8
∠7 & ∠1
Exterior angle pairs that lie on opposite sides of the transversal.
