If you have all points on both sides of the line, then what is the difference between that and the plane?

OpenStudy (mathstudent55):

A line divides a lane into three regions. 1. The line itself. 2. One half-plane. 3. The other half-plane.

OpenStudy (rootbeer003):

sorry im confused

OpenStudy (mathstudent55):

Your drawing is a depiction of a plane. Your plane appears as a parallelogram. A plane is really a flat surface that never ends.

OHH is it d?

OpenStudy (rootbeer003):

i reread the question and im thinking d

OpenStudy (mathstudent55):

Let me give you the example of a line. A line is a set of points that are all arranged in a straight way without curving. A line has infinite length. Since we don;t have infinite sized paper or computer screens, we represent a line with a segment with arrowheads to show it never ends.

OpenStudy (mathstudent55):

A plane is a flat surface that never ends. We often use a parallelogram to represent a plane, but a plane has infinite length and width.

OpenStudy (rootbeer003):

my final answer is c

OpenStudy (mathstudent55):

We don;t use arrowheads at the edges of the representation of a plane because it's impractical. When a line is drawn on a plane, the line goes on forever. Now the plane is separated into the line itself and two half-planes.

OpenStudy (mathstudent55):

The half plane is bounded by the line on one side, but the rest of the half-plane is not bounded because a plane is of infinite size.

OpenStudy (rootbeer003):

ah so c it is

The correct answer is D.
