b.The figure formed by two planes diverging from a common line. c.The rotation required to superimpose either of two such lines or planes on the other. d.The space between such lines or surfaces. e.A solid angle. 2.A sharp or projecting corner, as of a building. ...
Every triangle has three sides and three angles on the inside. These angles add up to 180° for every triangle, independent of the type of triangle. In a right triangle, one of the angles is exactly 90°. Such an angle is called a right angle. To calculate the other angles, we need ...
Each ratio of each pair of lines corresponds to a particular angle, and these ratios are tabulated along with the angles they define. If you can measure the lengths of at least two of the sides of a right triangle, all you have to do is calculate the sine, cosine or tangent of the a...
In a right triangle, one of the acute angles is 30 degrees. What is the measure of the other acute angle? A. 30 degrees B. 45 degrees C. 60 degrees D. 90 degrees 相关知识点: 试题来源: 解析 C。解析:直角三角形两个锐角和为 90 度,一个锐角为 30 度,另一个锐角为 90 - 30 =...
