1. 1 Building Blocks of Geometry n n 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 continued n n 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 Collinear points are points on the same line. n Coplanar points are points on the same plane. n

1. 1 continued n 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.

1. 1 continued n 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.

1. 1 continued To bisect an object means to cut it in half. n A midpoint of a segment is a point that is halfway between the endpoints. A midpoint bisects the segment. n

1. 1 continued n There are two ways to write “the length of segment AB is” AB or BA n congruent Two segments are if they have the same length. The symbol for is congruent to” is_____. Never use a congruent symbol with a number!!!
