If a rectangular piece of paper ABCD. Point M is the midpoint of the diagonal AC, and point E is on the side of BC, fold △DCE along the line DE so that point C falls on the diagonal AC at point F , connect DF, EF. If MF=AB, then ∠DAF =? degree.

I can't show because I don't know how to make images at  

Step-by-step explanation:

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
