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 ...
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。
What are the complement and supplement of: (y + 20) . Complementary and Supplementary : Complementary angles are two angles who, when added up, equal 90. On the other hand, supplementary angles are two angles that total 180. We use these definitions to solve this question. Answer and Expla...
Whenever lines, rays, or line segments intersect, angles are created. Angles are found in the area between the two intersecting lines, next to the point where they intersect. Depending on how the lines intersect, the angles will have different degree measurements....
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 ...
the sum of all the angles on one side of a straight line is always equal to 180 degrees, the sum of all the angles around the point is always equal to 360 degrees. angle examples question 1: find the unknown angle x for the given triangle abc, where ∠a = 28° and ∠b = 91°...
To prove the theorem, one other relationship between angles created by the lines must be accepted as a postulate. In this form of the proof the interior angles are treated as consecutive angles of a parallelogram since the lines are parallel. The corresponding angles a c are equal. In this ...
The two experiences are complementary and may be better than either alone. It has to be said that all therapy is open to abuse, particularly by enthusiastic but untrained people, but also by experienced people who should know better. The safeguard against this is to make sure that the ...

which the line segments at each point are perpendicular to one another; this means that each interior angle measures 90°. A square, defined as a rectangle with four equal sides and four equal angles, is a specific type of rectangle; each interior angle of a square therefore also measures ...
