Thanks for replying. As can be seen in the Scene Tree, the Tongue has a Collision Shape (a small dot in the middle of the Tongue...). When a collision is detected, a signal is sent to the Script. If the collision is with a Hole (an equally small dot in its centre...), The piece can be fixed in position (Connect flag is true...) so can no longer be Dragged, and will turn Red. This is where the angle of the other piece needs detecting, so that the Connecting piece can align itself. The angle difference can be any of the eight 45° angles that the pieces can adopt. Here's all the code...
