| Theorem of Pythagoras: |
a² + b² = c²
c² - b² = a²
c² - a² = b²
c = √(a² + b²)
a = √(c² - b²)
b = √(c² - a²)
|
| Hypotenuse sector p: |
p = ( a² ) / c
|
| Hypotenuse sector q: |
q = ( b² ) / c
|
| Height h: |
h = √(p * q )
|
| Perimeter: |
a + b + c
|
| Surface area: |
( a * b ) / 2
|
| Angles: |
α = arccos( (b² + c² - a²) / 2bc )
β = arccos( (a² + c² - b²) / 2ac )
γ = 90 °
α + β = 90 °
