Answer:
True.
Step-by-step explanation:
A rhombus has four side of the same length (sometimes) and bisecting diagonals.
A square has what a rhombus has, as well as what a rectangle has.
A rectangle has parallel sides, four right angles, and congruent diagonals.
That means that a square has four right angles, four sides of the same length, and bisecting diagonals.
That's why a square is a rhombus and a rectangle but not its converse.
So, true.
