MATH LESSON

Points, lines, and planes have no formal definition but they are the foundation of geometric figures such as angles, polygons, and solids. Such are called?

Undefined Terms

It can be best described as an exact location, an intersection, or a corner.

Point

may be visualized as a straight string that has no start and no end. Thus, It also has no length.

Line

It is a part of a line from one point to another point. These two points are called endpoints. The length of it can also be determined.

Line Segment

It is also a part of a line from a point and it goes to one direction. And has only one endpoint. Thus, the length of it cannot be determined.

Ray

When there are two non-opposite rays that intersect at a common endpoint, they form a figure called an?

Angle

can be visualized as a flat surface that extends infinitely in all directions. It is two dimensional (that is, length and width) but has no thickness.

Plane

Points that are contained in one line are called?

Collinear Points

Points that are not contained in one line are called?

Noncollinear Points
