Lesson 3.1
Lines Cut By A Transversal
Lesson 3-1
Transversal – 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.

Vocabulary
 Vertical 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
Vocabulary
 Alternate 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
Identify
as alternate interior, alternate exterior,
corresponding, or consecutive interior angles.
Answer: corresponding
Identify
as alternate interior, alternate exterior,
corresponding, or consecutive interior angles.
Answer: alternate exterior
Identify
as alternate interior, alternate exterior,
corresponding, or consecutive interior angles.
Answer: corresponding
Identify
as alternate interior, alternate exterior,
corresponding, or consecutive interior angles.
Answer: alternate exterior
