Measuring Angles: Angles with measures more than 360 DegreesThis lesson will help students explore angles that are more than 360 degrees, or less than -360 degrees.Tom De Vries
A. equilateral triangle B. isosceles triangle C. right triangle 相关知识点: 试题来源: 解析 C。有一个角是 90 度的三角形是直角三角形,同时两个 45 度角的边相等,也是等腰三角形,但本题主要强调直角,所以答案是 right triangle。反馈 收藏
When measuring the angle of a prism in a physics experiment, you find that one angle is 60 degrees. What is the sum of all angles inside the prism? A. 120 degrees B. 180 degrees C. 360 degrees D. 720 degrees 相关知识点: 试题来源: 解析 C。解析:多边形内角和公式为(n - 2)×18...
A. 70 degrees B. 80 degrees C. 90 degrees D. 100 degrees 相关知识点: 试题来源: 解析 C。本题考查三角形内角和为 180 度。已知两个角分别为 30 度和 60 度,那么第三个角为 180 减去 30 再减去 60 等于 90 度。反馈 收藏
A triangle has angles measuring 30 degrees, 60 degrees and ___ degrees. A. 70 B. 80 C. 90 D. 100 相关知识点: 试题来源: 解析 C。三角形内角和是 180 度,已知两个角分别是 30 度和 60 度,所以第三个角是 180 减去 30 再减去 60 等于 90 度,选 C。A、B、D 选项的角度值都不符合三...

A triangle has angles measuring 30 degrees, 60 degrees, and 90 degrees. What is the ratio of the sides opposite these angles? A. 1:2:3 B. 1:√3:2 C. 2:1:√3 相关知识点: 试题来源: 解析 B。在 30-60-90 度的直角三角形中,边长比为 1:√3:2。
then, you can drog the protractor or add pushpins to figure out the degrees of angles, upload file only accept image file, formats (jpg,jpeg,gif,png) In the control panel, if the background color is close to the protractor, and it's not easy to distinguish, you can change a ...
Types of Angles Right Angle A right angle has a measurement of 90 degrees, which is written 90°. This means that one side is perfectly flat, or horizontal, and the other is going straight up and down, or vertical. You can see an example in the picture below. You see this type of ...
