This page illustrates a few specific figures: Figurehead, Stork Line, Oblique Line, and Sit.

Figurehead	Lady's Oblique Line (man split)

A figurehead is any of a number of "up" positions, with high and forward poise, usually assumed by the woman and more or less resembling the wooden female figureheads of ships of old.
	In the figurehead, the woman's feet may be together, or she may lunge or extend one leg, yielding a variety of styles.
		Here, we have a stork line, which is a figurehead in which one leg is raised to the supporting knee, toes pointing down. I suppose it is a styalized representation of a resting stork.	And, take another look at the oblique line above. It has a stork quality in its raised foot, but the oblique line stretches the oblique abdominal muscles and so produces a graceful curve to the whole body.
A sit usually involves a small back step and then a relaxing of the knees and a consequent lowering of the body as if beginning to sit down.	Sometimes the sit can be quite extreme.		These picture figures give one a lot of latitude for individual expression.
