Chapter 3. 1-7

1. Describes lines
that intersect at 90° 1. Perpendicular

2. Describes lines
in the same plane
that never intersect 2. Parallel

3. A line that divides a
line segment in half
and is at right angles 3. Perpendicular Bisector
(90°) to it

4. A line that divides a
angle into two equal parts 4. Angle Bisector

5. A part of a line between
two endpoints 5. Line Segment












6. Which of the following are parallel
and which are perpendicular?

Parallel lines are lines that never cross or intersect.
Ex:



















Perpendicular lines are lines that intersect at a 90° angle.









7. Copy these line segments into your
notebook. Draw two perpendicular line
segments and two parallel line segments for each

A perpendicular bisector is this:
