A rhombus is defined as a parallelogram with four equal sides. Is a rhombus always a rectangle? No, because <u>a rhombus does not have to have 4 right angles.</u> Kites have two pairs of adjacent sides that are equal.
A rhombus has four congruent sides, and does not necessarily have to have right angles. (A square is considered a rhombus and has four right angles, so that is the only exception). So, your answer would be rhombus!
