Every triangle has three sides and three angles on the inside. These angles add up to 180° for every triangle, independent of the type of triangle. In a right triangle, one of the angles is exactly 90°. Such an angle is called a right angle. To calculate the other angles, we need ...

1. 三角形的角 (Angles in Triangles) 三角形的内角和为180度,这是三角形的重要性质之一。根据不同的角度,三角形可以分为: 锐角三角形 (Acute Triangle):三个内角均为锐角。 直角三角形 (Right Triangle):有一个内角为直角。 钝角三角形 (Obtuse Triangle):有一个内角为钝角。 2. 四边形的角 (Angles in ...
When you choose which of the two angles (ø) in a right triangle you want to find, you establish three sides in relation to it. The line that touches the angle and extends to the 90-degree angle is called the adjacent side, while the side opposite the angle is the opposi...
Complementary angles in a right triangle Take a look at a right triangle's height – did you notice that altitude, h꜀, from the right angle to the hypotenuse creates two similar triangles? The adjacent complementary angles also have the same measures as the angles in the original right tri...
In a right triangle one angle is of \(90^\circ \). The longer side of the right triangle which is opposite to the right angle is known as hypotenuse.Straight Angle:When the arms of the angles lie in the opposite direction, they form a straight angle. That is, an angle of \(180^...
In a right triangle, one of the acute angles is 30 degrees. What is the measure of the other acute angle? A. 30 degrees B. 45 degrees C. 60 degrees D. 90 degrees 相关知识点: 试题来源: 解析 C。解析:直角三角形两个锐角和为 90 度,一个锐角为 30 度,另一个锐角为 90 - 30 =...
In a right triangle, one of the acute angles measures 45 degrees. What is the measure of the other acute angle? A. 45 degrees B. 60 degrees C. 30 degrees D. 90 degrees 相关知识点: 试题来源: 解析 A。在直角三角形中,两个锐角的和是 90 度。已知一个锐角是 45 度,那么另一个锐角...
