Which description does not guarantee that a quadrilateral is a kite? a. perpendicular diagonals b. perpendicular diagonals, exactly one of which bisects the other c. one diagonal bisects opposite angles and the other diagonal does not d. two distinct pairs of congruent adjacent sides

The correct option is A.

Step-by-step explanation:

The properties of a kite are:

a) Two distinct pairs of consecutive congruent sides.

b) Two perpendicular diagonals.

c) Short diagonal is cut by the long diagonal.

d) The non-vertex angles are congruent.

e) A diagonal bisects the vertex angles.

The following quadrilateral have perpendicular diagonals:

(1) Rhombus, (2) Square, (3) Kite

The description "perpendicular diagonals" does NOT guarantee that a quadrilateral is a kite.

Therefore the correct option is A.

answer:

a=9
