hypotenuse
Significado: The longest side of a right-angled triangle, located opposite the right angle.
The hypotenuse is central to Pythagoras' theorem, which states that the square of the hypotenuse equals the sum of the squares of the other two sides. It is also essential for defining trigonometric ratios: sine, cosine, and tangent all involve the hypotenuse. The word is exclusively used in geometric and mathematical contexts.
Ejemplos
- Using Pythagoras' theorem, she calculated the length of the hypotenuse to be thirteen centimetres. 利用勾股定理,她算出斜边的长度为十三厘米。Aplicando el teorema de Pitágoras, calculó que la longitud de la hipotenusa era de trece centímetros.ピタゴラスの定理を使い、彼女は斜辺の長さが13センチメートルであると算出した。피타고라스의 정리를 사용하여 그녀는 빗변의 길이가 13센티미터임을 계산했다.
- The hypotenuse is always the side opposite the right angle in a triangle. 斜边总是三角形中直角对面的那条边。La hipotenusa es siempre el lado opuesto al ángulo recto en un triángulo.斜辺は三角形において常に直角の対面にある辺である。빗변은 삼각형에서 항상 직각의 맞은편에 있는 변이다.
- He labelled the hypotenuse on the diagram before working out the trigonometric ratios. 他在图上标注了斜边,然后再计算三角比。Etiquetó la hipotenusa en el diagrama antes de calcular las razones trigonométricas.彼は三角比を求める前に図の斜辺にラベルをつけた。그는 삼각비를 구하기 전에 도형에서 빗변에 표시를 했다.
