3. There are 3 undefined terms in geometry: point, line, and plane. These terms can be described but they can’t be defined. A point is a “dot”. It has no size, just a location. A point is named by using a capital letter. 1.1 Building Blocks of Geometry

4. A line is made up of an infinite number of points and is considered to be straight. To name a line, pick any two points on the line (in any order) and place a ↔ above them. A plane is a flat surface that extends infinitely along its width and length. To name a plane, a script capital letter is used. 1.1 continued

5. Collinear points are points on the same line. Coplanar points are points on the same plane.

6. 1.1 continued A ray is a part of a line that starts at a point called its endpoint, and then extends infinitely in one direction. To name a ray, you need two points. The first point is its endpoint. This indicates where the ray starts. The other point is any other point on the ray. You then put a → symbol above those two points.

7. 1.1 continued A line segment is a part of a line with a beginning and an end. The point at the beginning and the point at the end are called the endpoints. To name a segment you use its endpoints (in either order) then place a − symbol above them.

8. 1.1 continued To bisect an object means to cut it in half. A midpoint of a segment is a point that is halfway between the endpoints. A midpoint bisects the segment.

9. 1.1 continued There are two ways to write “the length of segment AB is” Two segments are if they have the same length. The symbol for is congruent to” is_____. Never use a congruent symbol with a number!!! AB or BA congruent
