The answer is D. False; all rhombuses do not have four 90° angles.

all rhombuses do not have four 90° angles because it may 89° below or 180° above

a rhombus is a quadrilateral in which all of the sides are of equal length, i.e., it is an equilateral quadrangle. If any angle of an equilateral quadrangle is a right angle, then all its angles are right angles and it is also a square.
