1. Chapter 1 Section 2

2.  Students will understand basic terms and postulates of Geometry.

3.  A specific location in space  It has no size, width, or depth  It is named by a Capital Letter

4.  An infinite collection of points in a straight path that extends forever in two directions.  Has no size, width, or depth  It is named by any two points on the line or by a lower case cursive letter.

5.  A flat surface that extends forever without end in four directions.  It is named by a any three points on the plane or by a capitol cursive letter.  It has no size, width, or depth

6.  Points on the same line  Can be used to name the line

7.  On the same plane  Remember: a plane contains an infinite number of points and lines.

8.  Look at Problem 1  Try the “Got It” problem for this example.

9.  The set of all points in three dimensions.  It contains the universe =)

10.  Part of a line  It has a definite beginning and an end  It is named by its two endpoints. AB

11.  Half of a line  It extends forever in one direction and has one endpoint.  It is named by its endpoint and any other point on the ray. A B

12.  Two rays that share the same endpoint and extend in opposite directions  It makes a line

13.  Look at Problem 2…  Try the “Got It” Problems

14.  An accepted statement of fact  Also known as an axiom  Basic building block of Geometry

15.  Through any two points there is exactly one line

16.  The set of points two figures have in common  Where the two figures overlap

17.  Two lines intersect at a point

18.  Two planes intersect at a line

19.  Look at Example 3…  Try the “Got It” problem for that example.

20.  Through any three noncollinear points there is exactly one plane

21.  Look at Example 4…  Try the “Got It” problem for that example

22.  Try Problems #1-7 on your own.  Raise your hand when you have completed them.
