# Parallel And Perpendicular Lines Worksheet

Parallel and
Perpendicular Lines
Key Vocabulary
Lessons 3-1, 3-2, and 3-5 Identify angle
relationships that occur with parallel lines and a
parallel lines (p. 126)
transversal, and identify and prove lines parallel
transversal (p. 127)
from given angle relationships.
slope (p. 139)
Lessons 3-3 and 3-4 Use slope to analyze a line
equidistant (p. 160)
and to write its equation.
Lesson 3-6 Find the distance between a point
and a line and between two parallel lines.
The framework of a wooden roller coaster is composed of millions
of feet of intersecting lumber that often form parallel lines and
transversals. Roller coaster designers, construction managers, and
carpenters must know the relationships of angles created by parallel
lines and their transversals to create a safe and stable ride.
You will find how measures of angles are used in carpentry and
construction in Lesson 3-2.
