What is a plane

The video tutorial introduces the basic geometric concepts of points, lines, and planes. A point is defined as having no size, while a line is made up of infinite points and has no thickness. A plane is described as a flat surface extending infinitely, composed of infinite lines. The tutorial also covers how to label these geometric figures, emphasizing that a plane can be labeled using three points.

What is a characteristic of a point?

• It has thickness.

• It has a definite size.

• It is made up of lines.

• It has no size.

Which of the following is true about a line?

• It has a definite length.

• It is made up of planes.

• It contains infinitely many points.

• It has thickness.

What is a plane composed of?

• A single line

• Infinite lines

• Finite points

• A single point

Why does a plane have no thickness?

• Because it is a three-dimensional object.

• Because it is made up of lines, which have no thickness.

• Because it is made up of lines, which have thickness.

• Because it is made up of points, which have size.

How can a plane be labeled?

• With four capital letters

• With two capital letters

• With three capital letters

• With a single capital letter
