Oriented in a direct up-to-down (or visa versa) manner from any fixed Point of Reference.

Comments:

Vertical is generally associated with relative direction or orientation in relation to self or any fixed Point of Reference, such as the earth, where the primary measurable element is from top-to-bottom (or visa versa).

Vertical is most generally directly related to the dimension of height.

Vertical, as associated with self, is derived by standing straight and looking straight ahead with vertical being represented by drawing a line in a direct up-to-down (or visa versa) direction.

A vertical plane can also be accomplished using a different Point of Reference in the environment by orienting it in a line directly from top-to-bottom (or visa versa) of that element. But typically, and under normal circumstances, vertical is most commonly used in relation to either self or the earth.

Vertical is one of the three primary orientations used in American Kenpo. The other two being: horizontal and diagonal.

Using the earth as the Point of Reference, vertical is perpendicular to the plane of the horizon.

One way to conceptualize a vertical plane, is to visualize a line starting from your head and ending at the ground, bisecting your body in half from left to right. In other words, a line that directly follows your centerline.

Example(s):

Using the clock principle, an example of a vertical plane would be a line from 12:00 - 6:00 or 6:00 - 12:00; with the clock standing on its side and oriented directly in front of you.

Using the directional zone theory, an example of a vertical plane would be from front, upper; to front, middle; to front, lower (or visa versa).
