__Math Tutoring on Points, Lines and Planes__

*Point: *

A **Point**** **is an exact location in space. They are shown as dots on a plane in 2 dimensions or a dot in space in 3 dimensions. It is labeled with capital letters. It does not take up any space.

*Line: *

A **Line**** **is geometric figure that consists of an infinite number of points lined up straight that extent in both directions forever. A **Line** is identified by a lower case letter or by using two points the line passes through.Two **Lines** are either **Parallel** or **Intersection.**** ****Parallel Lines** never touch each other. **Intersecting Lines** do touch each other.

There is exactly 1 line through two points. All points on the same **Line** are called **Collinear.** Points not on the same **Line** are **Noncollinear.**

*Plane:*

**Plane**** **is a flat 2 dimensional surface. A **Plane** can be identified by 3 points in the **Plane****.** There is exactly 1 **Plane** through three points. The intersection of two **Planes** is a line.

*The Ruler Postulate*

The distance between two points is the absolute value of the difference between the real numbers shown on a ruler.

*Segment Addition Postulate*
