v_angle_sign_2D

static GeometryOperators.v_angle_sign_2D(va: list, vb: list, right_handed: bool = True) → float

Evaluate the signed angle between two 2D geometry vectors.

It is the 2D version of the GeometryOperators.v_angle_sign considering vn = [0,0,1]. In case of opposite vectors, it returns an angle equal to 180deg (always positive).

Parameters:

vaList

List of [x, y] coordinates for the first vector.

vbList

List of [x, y] coordinates for the second vector.

right_handedbool

Whether to consider the right-handed rotation from Va to Vb. The default is True. When False, left-hand rotation from Va to Vb is considered.

Returns:

float

Angle in radians.
