## What is named using two letters?

A ray is part of a line having one endpoint and a set of all points on one side of the endpoint. A ray is always named by using two letters of choice. The first letter must be the endpoint. We draw an arrow with an endpoint over the letters.

## What is an example of a point?

What does coplanar and Noncollinear mean?

Non-collinear points: These points, like points X, Y, and Z in the above figure, don’t all lie on the same line. Coplanar points: A group of points that lie in the same plane are coplanar. Non-coplanar points: A group of points that don’t all lie in the same plane are non-coplanar.

What is an example of a plane in real life?

Examples of a plane would be: a desktop, the chalkboard/whiteboard, a piece of paper, a TV screen, window, wall or a door.

### Can a line be named by ONE SMALL LETTER?

A line may also be named by one small letter (Figure 2). Two lines. Points that lie on the same line are called collinear points. If there is no line on which all of the points lie, then they are noncollinear points. In Figure 3 , points M, A, and N are collinear, and points T, I, and C are noncollinear.

How do you name a portion of a line?

A portion of a line that begins with a single point (endpoint) and extends infinitely in one direction. It can be named using two capital letters standing for points on the figure. The endpoint must be the first letter in its name.

How many words can you name with two capital letters?

An infinite number of points that extend infinitely in two opposite directions. It is straight and has only one dimension. In representation, it can be named with two capital letters representing two points on it, or with one lower case letter. Nice work! You just studied 29 terms!
