  2. Theorem Theorem 6.9: Each diagonal of a rhombus bisects two angles of the rhombus.

  3. Theorem Theorem 6.10: The diagonals of a rhombus are perpendicular.

  4. Applications Find the measures of the numbered angles of the rhombuses.

  5. Theorem Theorem 6.11: The diagonals of a rectangle are congruent.

  6. Applications Find the length of segment FD in rectangle GFED if FD = 3y + 4 and GE = 6y – 5.

  7. 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.

  8. Applications Can you conclude that the parallelogram is a rhombus or a rectangle? Explain.
