Lesson 3.1 Lines Cut By A Transversal
Lesson 3-1Transversal – A line that intersects
two or more coplanar lines at different points Skew lines- lines that do not intersect and are
not coplanar.

Answer:
BUS STATION Some of a bus station’s driveways are shown. Identify the sets of lines to which line v is a transversal.
Answer: If the lines are extended, line v intersects lines u, w, x, and z.

Answer: lines a, b, c, e, f
VocabularyVertical Angles – non-adjacent, non-
overlapping congruent angles formed by two intersecting lines . (They share a common vertex.)
Linear Pairs of Angles –two adjacent angles whose non-shared rays form a straight angle
Corresponding Angles – angles that lie on the same side of the transversal and in corresponding positions relative to the parallel lines
VocabularyAlternate Interior Angles – nonadjacent
angles between the parallel lines that lie on opposite sides of the transversal
Alternate Exterior Angles – nonadjacent angles outside the parallel lines that lie on opposite sides of the transversal
Same-Side Interior Angles – angles that lie on the same side of the transversal and between the parallel lines
