Unit 3– Quadrilaterals Review for Final Exam

2
True/False A diagonal is a line segment in a polygon that connects any two vertices.

3
True/False If the sum of the lengths of two consecutive sides of a kite is 48 cm, then the perimeter of the kite is 96 cm.

4
True/False If the vertex angles of a kite measure 48° and 36°, then the nonvertex angles each measure 138°.

5
True/False The diagonals of a rectangle are perpendicular bisectors of each other.

6
True/False A trapezoid is a quadrilateral having exactly one pair of parallel sides.

7
True/False A polygon with ten sides is a decagon.

8
True/False A square is a rectangle with all the sides equal in length.

9
True/False A pentagon has five sides and six diagonals.

10
True/False Any two consecutive sides of a kite are congruent.

11
True/False If a polygon has two pairs of parallel sides then it is a parallelogram.

12
True/False The diagonals of a parallelogram are congruent.

13
True/False The measure of each angle of a regular dodecagon is 150°.

14
True/False If the sum of the measures of the interior angles of a polygon is less than 1000°, then the polygon has fewer than 7 sides.

15
True/False The sum of the measures of one set of exterior angles of a polygon is always less than the sum of the measures of the interior angles.

16
True/False Both pairs of base angles of an isosceles trapezoid are supplementary.

17
True/False The diagonals of a rhombus bisect the angles of the rhombus.

18
True/False If the diagonals of a quadrilateral are congruent, but only one is the perpendicular bisector of the other, then the quadrilateral is a kite.

19
True/False If the diagonals of a quadrilateral are congruent and perpendicular then it is a square.

20
True/False The consecutive angles of a rectangle are congruent and supplementary.

21
True/False The diagonals of a rectangle bisect the angles.

22
True/False A square is a rhombus with all angles congruent.

23
True/False Every rhombus is a square.

24
True/False It is not possible for a trapezoid to have three congruent sides.

25
True/False Every square is a rectangle.

26
True/False A diagonal divides a square into two isosceles right triangles.

27
True/False Opposite angles in a parallelogram are always congruent.

28
**Always/Sometimes/Never**

An equilateral polygon is equiangular.

29
**Always/Sometimes/Never**

The diagonals of a kite are perpendicular bisectors of each other.
