In the applet below to move the point A vertically click it once and drag it upwards or downwards.To move it horizontally click it again and then drag horizontally . Observe how the coordinates change. You can rotate the planes as well.
The Coordinates and the Coordinate planes
How should we refer the y-z plane?
How should we refer the z-x plane?
In what way you can describe all the upper four octants?
In what way you would express the lower four octants?
Drag the point B (Red) along the x-axis and study the coordinates of the eight vertices of the cube .
Which of the points below lie on the x-axis?
Which of the points below lie on the y-axis?
Which point below lies on the z-axis?
Which point below lies on the x-y plane?
Which point below lies on the y-z plane?
Which point below lies on the z-x plane?
