1. it is either rhombus or square - in either case, the sides are equal
2. it is impossible to have a parallelogram in which 3 sides are equal, and the fourth one to be of a different size.

Statement 1

By DEFINITION- IF a four sided figure has two diagonals that are perpendicular bisectors THEN the figure MUST be a rhombus. A rhombus has four equal sides.

Suff

Statement 2

Clearly suff
