Side Lengths of a Right Triangle Reproduced as Perimeters of Other Right Triangles: A Sketch and ProofKaufman, RichardOhio Journal of School Mathematics
right triangle- a triangle with one right angle right-angled triangle triangle,trigon,trilateral- a three-sided polygon hypotenuse- the side of a right triangle opposite the right angle oblique triangle- a triangle that contains no right angle ...
To find one of the angles, choose the formula that can be used given the two known side lengths, then substitute the known values in the formula and solve. For example,let’s find the angle of a triangle if the adjacent side length is 7 and the hypotenuse is 15. ...
Triangle ABC is a right triangle with the side lengths shown. What is the length of BC?Since i cant show the actual triangle i hope it will help if i mention that line BA of the triangle is 5 and so is line AC A) 2√5 B) 5√2C) 10 D) 25 I beile...

The length of the hypotenuse is 6. To find this result: Calculate the sine of α: sin(α) = sin(30°) = 1/2. Apply the following formula: sin(α) = opposite/hypotenuse hypotenuse = opposite/sin(α) = 3 · 2 = 6. That's it! Can I apply right-triangle trigonometric rules in ...
To solve a triangle with one side, you also need one of the non-right angled angles. If not, it is impossible: If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle. Alternatively, multiply the hypotenuse by cos(θ) to get the side...
right-angled triangles, and obtuse triangles. A right-angled triangle is a triangle that has one angle equal to 90 degrees. The sides of the right-angled triangle are referred to as the hypotenuse (longest side), and the legs (other two sides). A right-a...
In a right triangle, if one angle is 45 degrees and one side is 5, what is the length of the other side? A. 5 B. 5√2 C. 10 D. 5√3 相关知识点: 试题来源: 解析 A。因为是 45 度的直角三角形,所以两直角边相等,所以另一条直角边也是 5 。
A right triangle has one angle that measures 90 degrees. What is the name of the side opposite the 90-degree angle? A. hypotenuse B. base C. height D. side 相关知识点: 试题来源: 解析 A。直角三角形中直角所对的边叫斜边,即 hypotenuse。B 选项 base 是底边,C 选项 height 是高,D 选项...
