Final answer:
Squares and rhombi have certain properties in common with other quadrilaterals, but also have unique properties.
Step-by-step explanation:
Squares and Rectangles:
Property of squares: Squares have four right angles, which is also a property of rectangles.
Property of squares: Squares have four congruent sides, which is NOT necessarily a property of all rectangles.
Squares and Rhombi:
Property of rhombi: Rhombi have four congruent sides, which is also a property of squares.
Property of rhombi: Rhombi have diagonals that are perpendicular to each other, which is NOT necessarily a property of all parallelograms.
Property of all parallelograms:
Property: Opposite sides are parallel and congruent.
