Calculating the measures of a right- angled triangle - Pythagorean theorem right- angled triangle right- angled

For right- angled triangles with a right angle by C is:
area = (a * b) / 2
a² + b² = c² (Pythagorean theorem)
a² = c * p, b² = c * q (Kathetensatz des Euklid)
h² = p * q (Höhensatz des Euklid)
sin Alpha = a / c
