point.angleBetween(p1, p2)
Compute the angle (in degrees) between the line from this point to p1
and the line from this point to p2
.
The ordering of points p1
and p2
is important. The function returns a value between 0 and 180 when the angle (in the direction from p1
to p2
) is clockwise, and a value between 180 and 360 when the angle is counterclockwise. The function returns NaN
if either of the points p1
and p2
is coincident with this point.
