Pythagorean Theorem
也称为: Pythagoras Formula, Right Triangle Formula
a^2 + b^2 = c^2
a² + b² = c²它计算什么
In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides.
变量
| 象征 | 姓名 | 描述 |
|---|---|---|
| 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 |
推导
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.
工作示例
1
c² = 3² + 4² = 9 + 16 = 252
c = √25 = 5结果: c = 5
