How to animate PathGeometery/Shape in wpf

Question

What is the right way to animate a shape to another shape?
I have two shapes created using Path. one shape is start point and the other is the end point. how would you animate these?
I have created shapes in another application and when i export them into xaml it gives me complex shape made of geometry path. but i dont know how to animate that.
is there any tool or application for this purpose?
note that animation is not position transformation. by animation i mean changing from triangle to square.
