## Right-angled Triangles

A right-angled triangle mostly is well-determined by two magnitudes and the right
angle. In the program you are asked to choose two of the following elements and
then to enter their values:

- Catheti a and b
- Hypotenuse c
- Angles α and β
- Hypotenuse sections p and q
- Altitude h
- Area A

If you enter the values of two out of these nine magnitudes the program computes the others.

### Example 1:

Given:
¯¯¯¯¯¯
Cathete a = 3
Hypotenuse c = 5
Results :
¯¯¯¯¯¯¯
Cathete b = 4
Angle α = 36,869898°
Angle β = 53,130102°
Hypot. segment p = 1,8
Hypot. segment q = 3,2
Altitude h = 2,4
Area A = 6

### Example 2:

Given:
¯¯¯¯¯¯
Hypot. segment p = 1,8
Area A = 6
Results :
¯¯¯¯¯¯¯
Cathete a = 3
Cathete b = 4
Hypotenuse c = 5
Angle α = 36,869898°
Angle β = 53,130102°
Hypot. segment q = 3,2
Altitude h = 2,4
