Trigonometric functions

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)

Get angle α of a right triangle formed by the given line
Parameters:
x1: x coordinate 1 (int - optional, required if argument l is not specified)
y1: y coordinate 1 (float - optional, required if argument l is not specified)
x2: x coordinate 2 (int - optional, required if argument l is not specified)
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)
