| Symbool | Naam | Beschrijving |
|---|---|---|
| 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 |
Afleiding
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.
