 opposite sides... opposite angles of a parallelogram are congruent. of a parallelogram are congruent. Diagonals... of a parallelogram bisect each other. if both pairs of opposite sides... of a quadrilateral are congruent, then the quadrilateral is a parallelogram. if one pair of opposite sides.. of a quadrilateral are both congruent and parallel then the quadrilateral is a parallelogram. if both pairs of opposite angles... of a quadrilateral are congruent, then the quadrilateral is a parallelogram. if the diagonals of a quadrilateral... bisect each other, then the quadrilateral is a parallelogram. If two lines... are parallel, then all points on one line are equisistants from the other line. if three... parallel lines cut off congruent segments on one transversal, then they cut off congruent segments on every transversal. a line... that contains the midpoint of one side of a triangle and is parallel to another sire passes through the midpoint of the third side. The segment... that joins the midpoints of two sides of a triangle 1) is parallel to the third side 2) is half as long as the third side diagonals of a rhombus diagonals of a rectangle each diagonal of a rhombus are congruent are perpendicular. bisects two angles of the rhombus. THe midpoint of the hypotenuse... of a right triangle is equidistant from the three vertices. If two consecutive sides... of a parallelogram are congruent, then the parallelogram is a rhombus. Base angles of... If an angle of a parallelogram... a isosceles trapezoid are congruent. is a right triangle, then the parallelogram is a rectangle. the median of a trapezoid... is parallel to the bases has a length equal to the average of the bases.
