The correct option is B Statement 1 is true, while statement 2 is false.
Given the length of a diagonal of a square, we can calculate the length of the sides of the square. Further, since the angles of a square are known, a unique square can be drawn.
However, if only the measure of a side of a rhombus is given, an infinite number of rhombi can be drawn with varying interior angles.
Thus, statement 1 is true while statement 2 is false.
