The changeable form

A little brainteaser in beech plywood, 4 mm thick, cut by laser and sanded. Possibly the idea is a bit vintage, but the trick is still stunning.
All five parts should add up to a
Swiss cross,
a rhomb,
a rectangle,
a square,
a trapezoid
or a triangle.
Have a nice time puzzling it out!
