Pls experts answer ....fast or anyone ..

Dear Student.

We cannot prove that the quadrilateral formed is a square from the information you have given. It can be proven that it is a rhombus since all the sides are equal but to prove it a square, we need more information to conclusively say that it's a square. Recheck your question or please be a little specific so that we can provide you with some meaningful help.
Regards.
