Lesson Transcript
Instructor: Mark Boster
Points are important parts of math, and they can be used to label shapes and angles on a plane. Let's explore points a little further and take a look at some examples.

Defining a Point

Did you ever play the basketball game HORSE or PIG? You take a shot, and if you make it, the next player has to shoot from the exact same place, or the same point on the court. If the player misses, he or she is assigned a letter from the word 'horse' or 'pig'; whoever spells the complete word first loses.

As in a game of HORSE or PIG, a point in math is an exact location on a plane, usually marked by a dot. A plane is a 2-dimensional, flat surface. Many people think a point is a dot, but it's not -

the dot is simply used to show you the location of a point. Since a point is a location, it has no dimensions - only its position on a plane.


The dots represent points on the plane.

Labeling and Using Points

Often, you will see a point marked by not only a dot, but also labeled with a capital letter. Points are also used to mark the ends of lines, where the line segments are named after the points. It can be helpful to name points and line segments. This is especially true when there are more than one of them in the same area.


Point P, line segment AB, and line segment CD.
