Exhale raise the left arm up into this variation of Reverse Extended Side Angle.
呼气，抬左臂向上进入扭转侧三角伸展式。
You may only use elementary geometry, such as the fact that the angles of a triangle add up to 180 degrees and the basic congruent triangle rules (side-angle-side, etc.).
你可以使用初等的几何知识例如三角形的三个内角各为180度和三角形全等的规则(边-角-边等)。
Of the above the most important is the geometrical angle, because they measure time with price and show when the market is overbalanced on the up or down side.
在以上九个要点中最重要的是几何角度，因为他可以同时衡量时间和价格，并显示市场在上升或下降中是否超越平衡。
