Two angles are complementary. One angle is 30 degrees. What is the measure of the other angle? A. 60 degrees B. 45 degrees C. 30 degrees D. 150 degrees 相关知识点: 试题来源: 解析 A。互补角之和为 90 度,一个角为 30 度,另一个角为 90 - 30 = 60 度。
Two complementary angles are in the ratio of 2:3. What is the measure of the smaller angle? A. 36 degrees B. 54 degrees C. 72 degrees D. 108 degrees 相关知识点: 试题来源: 解析 A。互补角和为 90 度,设两角分别为 2x 和 3x,可得 2x + 3x = 90,解得 x = 18,所以较小角为 2x ...
Angles and Polygons An angle is formed when two lines (or line segments) meet at a single point. Angles are classified into distinct groups based on their measurement in degrees. Acute angles measure between 0° and 90°; obtuse angles measure between 90° and 180°. Right angles measure 9...
The measures of an angle are eight times the measure of its complementary angle. What is the measure of each angle? Complementary Angles: Two angles are said to be complementary to one another if the their sum is equivalent to 90 degrees. For exam...
What is an angle? Get the angle definition here at BYJU’S. Also, learn the different types of angles with many solved examples with a complete explanation.
The measure of an angle is 9 times the measure of its complementary angle. What is the measure of each angle? Complementary Angle: Any two angles are called complementary, when they add up to 90 degrees. They don't have to be next to each othe...
What Is an Angle? The word “angle” means the space (measured by the number of degrees) between two lines that create a common endpoint. In mathematics, there are different types of angle such as complementary angles, obtuse angles, acute angles, and reflex angles. ...
Two angles are complementary if the sum of the angles is equal to 90º (ninety degrees). For example, an angle that is 30º and an angle that is 60º are two complementary angles.Since 90º is the measurement for a right angle, another way to tell if two angles are ...
The parallel lines do not intersect. The line that crosses the parallel lines is called the transversal. The parallel lines are each a straight angle, which means that the line has a measurement of 180 degrees. The angles formed by the lines are either equal or they are supplementary, which...
They also form four pairs of linear pairs of angles. ∠∠1,∠∠3;∠∠1∠∠4;∠∠2,∠∠3;∠∠2,∠∠4 Linear pair of angles form a straight angle i.e., 180 degrees In a triangle ABC sum of angles∠A+∠B+∠∠A+∠B+∠C = 180 degrees ...
