In this lesson, we are going to go over some postulates that have to do with points, lines, and planes. A postulate is a statement that is assumed to be true; this is also called an axiom. Postulates are accepted as fact without having to be proved. The first postulate that we are going to go over: Through any two points, there is exactly one line. Similarly, there's a postulate that tells us about planes: Through any three points not on the same line, there is exactly one plane. You'll also learn about the postulates that tell you about the intersections of lines, and planes.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
