Answer 1

QUADRILATERAL

Question 2

Parallelogram: A quadrilateral that has exactly two pairs of opposite parallel sides.
-Rectangles, rhombuses, and squares are all special forms

Answer 2

PARALLELOGRAM

Question 3

The sides that are parallel are also _____. The opposite interior angles are always ______, and the consecutive interior angles are ______.

Answer 3

CONGRUENT
CONGRUENT
SUPPLEMENTARY

Question 4

The diagonals of a parallelogram ____ each other. Each diagonal divides the parallelogram into two congruent _____.

Answer 4

BISECT

TRIANGLES

Question 5

A quadrilateral that has exactly one pair of parallel sides. Some math texts define ____ as a quadrilateral that has at least one pair of parallel sides. Because there are no rules governing the second pair of sides, there are no rules that apply to the properties of the diagonals of a _____.

Answer 5

TRAPEZOID

Question 6

a parallelogram with 4 right angles

-the diagonals are congruent

Answer 6

RECTANGLE

Question 7

a parallelogram with 4 congruent sides

-the diagonals are perpendicular to each other

Answer 7

RHOMBUS

Question 8

a parallelogram with 4 right angles and 4 congruent sides

• All ____ are also parallelograms, rhombuses, and rectangles
• The diagonals of a ____ are congruent and perpendicular to each other.

Answer 8

SQUARE

Question 9

A quadrilateral whose diagonals bisect each other is a ____.
A quadrilateral whose opposite sides are parallel (2 pairs of parallel sides) is a ____.

Answer 9

PARALLELOGRAM

PARALLELOGRAM

Question 10

A quadrilateral whose diagonals are perpendicular bisectors is a ____. A quadrilateral whose opposite sides (both pairs) are parallel and congruent is a ____.

Answer 10

RHOMBUS

RHOMBUS

Question 11

A parallelogram that has a right angle is a ___. (Consecutive angles of a parallelogram are supplementary. Therefore, if there is one right angle in a parallelogram, there are four right angles in that parallelogram.)

Answer 11

RECTANGLE

Question 12

A rhombus that has a right angle is a ____. Because the rhombus is a special form of a parallelogram, the rules about the angles of a parallelogram also apply to the rhombus.

Answer 12

SQUARE
