The diagonals of a parallelogram meet at the point (0, 1). One vertex of the parallelogram is located at (1, 3), and a second vertex is located at (2, 0). Find the locations of the remaining vertices, and determine the most specific classification of this parallelogram.

The locations of the remaining vertices are at (−2, 1) and (−1, −2). The most specific classification of this parallelogram is a square.

The locations of the remaining vertices are at (−2, 1) and (−1, −2). The most specific classification of this parallelogram is a rhombus.

The locations of the remaining vertices are at (−2, 2) and (−1, −1). The most specific classification of this parallelogram is a square.

The locations of the remaining vertices are at (−2, 2) and (−1, −1). The most specific classification of this parallelogram is a rectangle.
