15. A rectangle is a quadrilateral with four right angles.
Rectangles
A rectangle is a quadrilateral with four right angles.

16. If a parallelogram is a rectangle, then its diagonals are congruent.
Theorem 6-9
If a parallelogram is a rectangle, then its diagonals are congruent.

17. Rectangle Property Summary

19. Rhombus
A Rhombus is a quadrilateral with four congruent sides.

20. Theorem 6-11
The diagonals of a rhombus are perpendicular.

21. Theorem 6-12 (Converse of Theorem 6-11)
If the diagonals of a parallelogram are perpendicular, then the parallelogram is a rhombus.

22. Rhombus
