The shoulders are well laid back at an angle of approximately 45; a line drawn from the highest point of the shoulder blade to the forward point of articulation approximates a right angle with a line from the forward point of articulation to the point of the elbow.

肩部向后倾斜，角度约45度；从肩胛最高点向前，到肩胛与前臂的结合点所形成的直线，与前臂从与肩胛结合点向下，延伸到肘部的直线，正好呈清晰的直角。

完整的齿系最为理想。nn 颈部 n 颈部的长度与身躯比例恰当，结实而略拱，平顺地与肩部结合。nn 前躯 n 肩部向后倾斜，角度约45度；从肩胛最高点向前，到肩胛与前臂的结合点所形成的直线，与前臂从与肩胛结合点向下，延伸到肘部的直线，正好呈清晰的直角。

If you examine the lake carefully, especially toward the right angle, you will notice two indentations.

In the construct process of area formulas for rectangles, right-angled triangles, and parallelograms, all six students appeared significant difference in perception ability.

一、在长方形、直角三角形和平行四边形等面积公式的建构历程，六名学童的「察觉能力不同」（察觉能力包括「察觉面积公式规则」和「发展心象切割拼补能力」）。

For example, omitting 'right angle' feature brings parallelograms under rectangles. The after called "underexatension" in the study, student can't understand relationship between graphs. For example, students don't think rectangles are one of the parallelograms.

前者往往是学童忽略一项属性的结果，例如忽略直角的特性，就会把斜长的平行四边形归类为长方形，而后者则因学童无法理解图形间包含关系的结果，例如把长方形排除在平行四边形的概念范畴之外。

A square has four 90-degree angles made by its four perpendiculars.

正方形有四个直角。

The man was of fine figure,swarthy,and stern in aspect;and he showed in profile a facial angle so slightly inclined as to be almost perpendicular.

男子身材魁梧，黑黝黝，严肃地样子，从侧面观擦，他的脸上线条僵硬，几乎成直角。

The general governing equation valid for both Cartesian and Cylindrical coordinates for fluid flow and heat transfer was discretized and coded with Fortran.

Of the importance of the Square of 8 and 9 grid relationship, Schwaller says, These two lengths, 8 and 9, are related to musical harmony. This is the tone in music and also the ratio between the diameter of a disk and the side of a square of the same surface area. The sum of 8 and 9 is 17, the famous number of Jabir [the famous Arabic alchemist of the 8th century C.E.].

对8方图和9方图的重要关系，古埃及考古学家，金字塔研究专家史沃乐先生说：这两个长度，8和9，和音律和谐规律是相关联的，它们是音乐中的调和与增强，也是一个圆的直径和等面积直角方形的边长的比率。8和9的和等于17，它是一个著名的阿拉伯术士在公元8世纪所使用的一个著名的数字。
