Prove that the quadrilateral is both a rectangle and a rhombus! Other Special Quadrilaterals Kite Trapezoid Isosceles Trapezoid Definition: A quadrilateral with exactly two pairs of consecutive, congruent sides. 6-6-1: Its diagonals are perpendicular. 6-6-2: Non-vertex angles are congruent One diagonal is the perpendicular bisector of the other. One diagonal bisects each vertex angle. Definition: A quadrilateral with exactly one pair of parallel sides. Consecutive angles between the bases are supplementary. The length of the midsegment is the average of the lengths of the two bases. Definition: A trapezoid whose non-parallel sides are congruent. Base angles are congruent. Diagonals are congruent.
