a^2 + b^2 = c^2
a² + b² = c²計算内容
In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides.
変数
| シンボル | 名前 | 説明 |
|---|---|---|
| a | Side a | One leg of the right triangle |
| b | Side b | Other leg of the right triangle |
| c | Hypotenuse | The longest side, opposite the right angle |
導出
Can be proven geometrically: arrange four copies of the right triangle into a large square. The inner square has side c, and its area c² equals the large square area minus the four triangle areas.
実用例
1
c² = 3² + 4² = 9 + 16 = 252
c = √25 = 5結果: c = 5
