Opposite angles are congruent. So we have a parallelogram right over here. The parallelogram has the following properties: Opposite sides are parallel by definition. The diagonals in a parallelogram. Thus you have a rhombus. According to … EASY. We need to prove that the parallelogram is the rhombus, in other words, that all four sides of the parallelogram have the same length. 5. Become a Study.com member to unlock this It is fairly easy to prove that the diagonals of a parallelogram (and therefore of the special parallelogram called a rectangle) bisect each other. The consecutive angles of a parallelogram are never complementary. Answer. The main difference is that a parallelogram has two parallel opposing sides which are of equal lengths, whereas a rhombus has four sides that all have equal lengths (all four sides are … Also opposite angles are equal (angles These properties concern its sides, angles, and diagonals. Are the diagonals of a parallelogram perpendicular? "D" is the best answer. Never The diagonals of a trapezoid are perpendicular. The quadrilaterals that have perpendicular diagonals are "square," "rhombus" and "kite."
