A. parallel B. perpendicular C. intersecting D. curved 相关知识点: 试题来源: 解析 C。本题考查形成角度的线条特点。intersecting 相交的,两条相交的直线会形成一个角度。parallel 平行的、perpendicular 垂直的、curved 弯曲的都不是形成角度的常见方式。反馈 收藏 ...
34. If two lines are parallel to each other, they are both at a right angle.相关知识点: 试题来源: 解析 两条平行线是在同一平面内永不相交的直线。直角是角度为 90 度的角。题干说两条平行线彼此成直角,这与平行线的定义相矛盾。因此,该陈述是错误的。 1. 定义平行线: 平行线是在同一平面内永...

If so, you probably remember that you used it to measure angles. The three basic kinds of angles areright angles,obtuse angles,andacute angles.If a basic geometric shape is made of straight lines (sorry, circles), it contains at least one of these three types of angles. ...
One strand focuses on different risk appetites of types of finance. Ghosh and Nanda (2010) have argued that the capital required for asset finance of the capital-intensive RE power plants is typically an order of magnitude larger than that which venture capitalists have been willing to supply ...
A parallel four-bar linkage was constructed for master–slave operation. During the experiment, the prosthesis was hung on a mechanical thigh with one degree of freedom to revolute the joint at the hip joint, as shown in the top part of Figure 15. The parallel four-bar linkage connects the...
