hypotenuse的音標是[ha?p??tenj?s]，基本翻譯是斜邊。速記技巧是利用簡寫的方式，可以記為“高因秀死”。

hypotenuse這個詞來源于希臘語，意為“腳的平方”。它的變化形式包括復數形式hypotenuses，過去式和過去分詞形式hypotenused或hypotenused，現在分詞形式hypotenus。

相關單詞：

1. right angle（直角）：這個詞由right（右邊的）和angle（角）組成，與hypotenuse有密切關系，因為直角是兩條邊的長度可以構成hypotenuse的角。

2. diagonal（對角線）：這個詞來源于拉丁語，意為“對角”，可以用來表示與直角成直角的線段，也就是hypotenuse。

3.bisect（二等分）：這個詞意為“二等分”，可以用來表示將線段或角分成相等的兩部分，這與hypotenuse的概念有關。

4.perimeter（周長）：周長是圍繞一個圖形一周的線的長度，對于三角形，其周長可能包括hypotenuse。

5.quadrant（象限）：在三角學中，一個角可以對應一個象限，而這個象限通常會考慮hypotenuse。

6.tangent（切線）：當一條線與角相切時，它可能與這個角有特定的關系，這可能涉及到hypotenuse的概念。

7.secant（正割）：secant與角的關系可能涉及到hypotenuse的概念，因為正割是使一個角的三角函數值保持常數的邊的長度。

8.arc（弧）：在幾何學中，弧線可能與hypotenuse有關，因為它是一個角的兩條邊的延長線。

9.radius（半徑）：半徑是圓心到圓周的距離，在三角學中，它可能與hypotenuse有關，因為三角形的hypotenuse是通過三角形的斜邊定義的。

10.slant_height（斜高）：斜高是與三角形的底邊垂直的線段，它可能與hypotenuse的概念有關。

hypotenuse的常用短語：

1. the hypotenuse of a right triangle

2. the length of the hypotenuse

3. measure the hypotenuse

4. the hypotenuse of a triangle

5. the hypotenuse of a right angle triangle

6. the hypotenuse of an acute angle triangle

7. the hypotenuse of an obtuse angle triangle

例句：

1. Can you measure the hypotenuse of this triangle?

2. The length of the hypotenuse of a right triangle is always equal to the square root of the sum of the squares of its other two sides.

3. The hypotenuse of an acute angle triangle is less than 90 degrees, while the hypotenuse of an obtuse angle triangle is greater than 90 degrees.

The Hypotenuse of a Triangle: Importance and Applications

The hypotenuse of a triangle plays a crucial role in geometry and other mathematical fields. It is the longest side of a right triangle, and it is also used to measure angles in trigonometry. The length of the hypotenuse varies depending on the angle formed by the other two sides, making it an essential tool in solving various problems.

In real-life applications, the hypotenuse of a triangle can be used in various fields, such as engineering, architecture, and surveying. For instance, engineers use trigonometry to calculate the height of a building or the distance between two points based on the measurements taken from two known points. Similarly, architects use trigonometry to design buildings that are structurally sound and aesthetically pleasing.

Moreover, the hypotenuse of a triangle is also used in other areas such as physics, astronomy, and even gaming. For example, gamers use trigonometry to calculate precise movements in first-person shooter games, while astronomers use it to measure the distance between stars and other celestial objects.

In conclusion, the hypotenuse of a triangle is an essential mathematical concept that plays a crucial role in various fields. It is used to measure angles, solve problems, and design structures that are both structurally sound and aesthetically pleasing. Understanding this concept is crucial for anyone who wants to pursue math-related careers or simply appreciate its diverse applications in real life.
