Answer 1

To prove that the vertices of a quadrilateral form a square, you can follow these steps:

1. **Prove that the vertices form a rectangle** by using one of the 4 methods (such as showing that opposite sides are equal and parallel, or that the diagonals are equal and bisect each other).

2. **Prove that the vertices form a rhombus** by also showing that all sides are equal in length.

By proving the quadrilateral is both a rectangle and a rhombus, you establish that the vertices form a square, as a square is defined as a quadrilateral that is both a rectangle and a rhombus.
