Given quadrilateral jklm with diagonals that bisect the vertices, what kind of quadrilateral is jklm? rhombus parallelogram trapezoid generic quadrilateral (no more specific classification can be determined)

 A rhombus is part of a parallelogram with four sides have the same length such as square. The diagonals of a rhombus is always bisect vertices and the diagonals of a parallelogram can bisect vertices if the 4 sides are congruent which really means that it is a rhombus.

the image of (6, 9) under a dilation is (4, 6). the scale factor is
