`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.
