7-1 Points, Lines, and Planes
Course 1
7-1 Points, Lines, and PlanesThe building blocks of geometry are points, lines, and planes.
A plane is a flat surface that plane LMN, extends without end in all plane MLN, directions. plane NLM
A plane is named by three points on the plane that are not on the same line.
M
N
L
A point is an exact location. P point P, P
A point is named by a capital letter. A line is a straight path that line AB, AB, extends without end in A B line BA, BA opposite directions.
A line is named by two points on the line.

A line segment is a line segment XY, XY, made of two endpoints Y line segment YX, YX and all the points between X the endpoints.
A line segment is named by its endpoints.
A ray has one endpoint. ray JK, JK From the endpoint, the ray J K extends without end in one direction only.
A ray is named by its endpoint first followed by another point on the ray.
