rt_get_angleAlpha(a, b, c, deg)
  Get angle α of a right triangle, given the lengths of its sides
  Parameters:
    a: length of leg a (float)
    b: length of leg b (float)
    c: length of hypotenuse (float)
    deg: flag to return angle in degrees (bool - default = false)
  Returns: angle α in radians (or degrees if deg == true)

    y2: y coordinate 2 (float - optional, required if argument l is not specified)
    l: line object (line - optional, required if x1, y1, x2, and y2 agruments are not specified)
    deg: flag to return angle in degrees (bool - default = false)
  Returns: angle α in radians (or degrees if deg == true)
