n.斜边，(直角三角形的)弦

原形：hypotenuse复数：hypotenuses

To find the length of the hypotenuse, we use the Pythagorean theorem.
要找到斜边的长度，我们使用勾股定理。
In a right-angled triangle, the hypotenuse is always the longest side.
在直角三角形中，斜边总是最长的一边。
The hypotenuse of an isosceles right triangle has a length of \( \sqrt{2} \) times one of the equal sides.
等腰直角三角形的斜边长度是其等边长度的\( \sqrt{2} \)倍。
After calculating, we determined that the hypotenuse measures 13 units.
经过计算，我们确定斜边长度为13单位。
In a 3-4-5 right triangle, the hypotenuse is 5 units long.
在一个3-4-5的直角三角形中，斜边长5单位。
If you know the lengths of the two legs of a right triangle, you can easily find the hypotenuse.
如果你知道直角三角形两条直角边的长度，你可以很容易地找到斜边的长度。
The hypotenuse forms a right angle with the other two sides of the triangle.
斜边与三角形的另外两边形成一个直角。
By applying trigonometric functions, we can also find the angles given the lengths of the sides including the hypotenuse.
通过应用三角函数，我们也可以根据包括斜边在内的边长来找到角度。
The square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.
斜边长度的平方等于另外两边长度平方的和，这是勾股定理的表述。
A ladder leaning against a wall forms a right triangle, with the ladder itself acting as the hypotenuse.
梯子靠在墙上形成的是一个直角三角形，梯子本身充当斜边。
