CONVERSES…
Theorem 6.12: If one diagonal of a parallelogram bisects two angles of the parallelogram, the parallelogram is a rhombus.
Theorem 6.13: If the diagonals of a parallelogram are perpendicular, the parallelogram is a rhombus.
Theorem 6.14: If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle.
Applications
Can you conclude that the parallelogram is a rhombus or a rectangle? Explain.
