Statement 1
Square and Rhombus both share this property. Insufficient
Statement 2
In rhombus opposite angles are equal so we can rule it out. Rectangle and square share this property but I believe GMAT considers Square as a special rectangle so it should be sufficient.

That's correct; a square is a type of rectangle. So, if the quadrilateral is a square, then we can also conclude that the quadrilateral is a rectangle.
From the Official Guide:
A parallelogram with right angles is a rectangle, and a rectangle with all sides of equal length is a square.
