What is the measure of a straight angle? A. 90 degrees B. 180 degrees C. 360 degrees D. 270 degrees 相关知识点: 试题来源: 解析 B。解析:straight angle 是平角,平角的度数是 180 度。选项 A90 度是直角的度数;选项 C360 度是周角的度数;选项 D270 度不是平角的度数。
For example, if you have an acute angle measuring 45°, it would be written as “∠ABC = 45°” where ABC are three points on the line forming the angle (the vertex and two others). Similarly, when you have a straight angle in your work, it should be written as “∠ABC = 180°...
The sum of two or more angles that are in this pair is always equal to 180°. We also call them linear pairs of angles. The image given above shows two angles ∠a = 125° and ∠b = 55°, which together form 180°. The straight angle has a common arm and a common vertex. In...
