### 1 Answer

1. Choose the quadrilateral that does not have at least one pair of consecutive sides congruent: a) rhombus b) kite c) isosceles trapezoid d) square.

Answer: **c) isosceles trapezoid **

All of the other quadrilaterals have more than one pair of consecutive sides congruent.

2. Choose the quadrilateral that may have exactly one pair of consecutive sides congruent: a) rhombus b) kite c) trapezoid d) square.

Answer: **c) trapezoid**

This happens when one of the parallel sides of the trapezoid becomes equal to one of the non-parallel sides. All of the other quadrilaterals have more than one pair of consecutive sides congruent.

3. Choose the item whose diagonals need not be congruent a) rhombus b) square c) rectangle d) isosceles trapezoid.

Answer:** a) rhombus**

All of the other quadrilaterals have congruent diagonals.

4. Choose the item whose diagonals bisect each other a) rhombus b) trapezoid c) kite d) isosceles trapezoid.

Answer: **a) rhombus**

Diagonals of all of the other figures bisect each other.

5. Choose the item whose diagonals need not be perpendicular: a) kite b) rhombus c) square d) parallelogram.

Answer: **d) parallelogram**

All of the other quadrilaterals have perpendicular diagonals

6. Choose the quadrilateral which need not have at least one pair of consecutive angles supplementary: a) trapezoid b) kite c) rhombus d) parallelogram.

Answer: **b) kite**

All the other figures have parallel opposite sides, hence have at least two pair of consecutive angles supplementary.

7. Choose the quadrilateral which must have exactly one pair of congruent angles: a) isosceles trapezoid b) parallelogram c) kite d) rhombus.

Answer: **c) kite**

The angles at the two intersections of junction of disjoint pair of sides are congruent. Others have more than one pair of congruent angles.
