Orthogonal

At right angles. Something is orthogonal if it is positioned or oriented 90° to something else. In Tensoku Ryu the line between angles one and two of the octagon is orthogonal to the line between angles three and four. Also the line between angles five and six is orthogonal to the line between angles seven and eight. And, if the octagon were laid on the floor with you at the center, then you would stand orthogonal to all of these other angles. So orthogonality exists in the x, y, and z directions.
