1) Is a rectangle a square?Is a square a rectangle?
2) If a rhombus a parallelogram?Is a parallelogram a rhombus?
PARALLELOGRAM Opp sides // Opp sides congruent Opp <‘s congruent Diagonals bisect each other Consecutive angles are supp.
RHOMBUS A rhombus is also a ___________________ so it has of their properties plus:
parallelogram
o All sides are congruento Diagonals are perpendicularo Diagonals bisect the angles
RECTANGLE A rectangle is also a _______________parallelogram
o All angles are congruento Diagonals are congruent
SQUARE
A square is also a ____________, a__________, and a______________
parallelogramrectangle rhombus
So it has all of their properties
