Conditions 

Quadrilateral(s)

Explain your reasoning

Diagonals are perpendicular.

Rhombus, Kite

 

 

Diagonals are perpendicular and only one diagonal is bisected.

Kite   

Diagonals are congruent and intersect but are not perpendicular.

Rectangle, Isos. Trap   

Diagonals bisect each other.

parallelogram   

Diagonals are perpendicular and bisect each other.

   

Diagonals are congruent, perpendicular and bisect each other

   

 

 

10.

 a parallelogram

opposite sides are parallel

-or

opposite sides are congruent

-or

diagonals bisect each other

b.rectangle

diagonals are congruent and bisect each other

-or

(c) a rhombus

 

diagonals are perpendicular and bisect each other

-or

opposite sides are congruent and diagonals bisect each other

a square

 

diagonals are congruent, perpendicular and bisect each other

-or

a kite

 

diagonals are perpendicular and one diagonal is bisected

or
