A is NOT true. Rectangles have angle measures of 90°, rhombuses don't have to.

B is true. A rhombus is a 4-sided shape where all side lengths are equal. so is a square.

C is true. All Parallelograms are 4-sided shapes, or quadrilaterals

D is untrue. Square require all side lengths to be equal. Rectangles do not.
