解析 By ASAT angles a and b add up to 90° because they are inscribed on a diameter. Thus we can say the angles are complementary.Mathematical ∠a+∠b=90°, also we know b=27°∠a+∠27°=90°∠a=∠90°=∠27°∠a=∠63° ...
In geometry, a right angle is an angle that bisects the angle formed by two halves of a line. The two halves of the line are called the legs of the angle. The vertex of the angle is the point where the two lines intersect. The sides of the angles are perpendicular to each other....
The term complementary is used to describe a relationship between the two angles; specifically, a relationship between the sum of their measures. We can have more than just a pair of angles that are complementary; for instance, there could be three angles that are complementary. Angles that...
What is an angle of 180 degrees called? What is an angle of 90 degrees called? In the figure, if \angle AOB= 140^\circ\ and\ \angle a= 50^\circ, what are \angle c\ and\ \angle d? What is the angle between v and w if: (a) v * w = -|| v || || w || (b) v ...
Barely had it come into existence, then the Moon was already exerting a powerful influence on the Earth because of its considerable size. The history of the Earth-Moon relationship has been studied very closely, thanks to the Apollo missions.月球还没有形成，就已经因其巨大的体积对地球产生了强大...
Right angle is a term used to describe a relationship between two lines or planes that meet at an angle of 90 degrees. It is also used as a measurement, denoting an angle that is exactly 90 degrees. This term is most commonly used in geometry, but it can also be applied to other are...
