Given a rhombus, a square, and a rectangle, what must be true of all three quadrilaterals?

A rhombus, a square, and a rectangle are all parallelograms. The diagonals of every parallelogram bisect each other, meaning they cross at a point that divides each diagonal into two equal segments. The diagonals do not have to be congruent or perpendicular in all three shapes, so the correct choice is B, “The diagonals bisect each other.”
