Chapter 8 Lesson 1
Taken from Mr. Hammond’s Website

2. Points
A point is a location in space. It has no size. It is named by a capital letter. .
Read it as: “Point A”
Write it as: “A” A

3. Lines
A line is a series of points that extends in two opposing directions without end. Lines have no thickness. Q S
Read it as: “Line QS” or “Line SQ”
Write it as: QS or SQ

4. Segments R B A segment is a part of a line with two endpoints.
Read it as: “Segment RB” or “Segment BR”
Write it as: RB or BR

5. Rays
A ray consists of an endpoint and all the points of a line on one side of the endpoint. C D
Read it as: “Ray CD” (the order does matter)
Write it as: CD

6. Intersecting
When two line segments, rays, or lines cross over each other they are said to intersect. E
We say there are two lines that intersect. C F G

7. Perpendicular
Are special intersecting lines. The point of intersection froms a right angle.
