To do this you need to think about it the bottom of the bigger shape fits with the bottom of the smaller triangle to make 1 then the 1 sides of the triangles can attach to the 1 other sides of the bigger shape so 2x1+1=3 so there are three possible solution. the reason only 1 side of the shape can match is because the angled side of the triangle is 0.5cm bigger then the 2 sides of the quadrilateral.
