Properties of rhombus: All opposite sides are parallel, opposite angles are equal, and diagnols bisect each other at 90 degress.

Stmt1: Suff

Stmt2: Could be a rectangle

PS: Some of you thinking, why can't it be a square ? well, a square can be a rhombus right ?

E it is

Statement 1 says that the 2 diagonals are perpendicular .... The quadrilateral could be a rhombus or a kite (one diagonal longer than other, but perpendicular to each other)
