Pythagoras Formulas

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 °

Hypotenuse: c
Catheti (legs): a,b
