For parallelogram EFGH, solve for x.

• 3

• 6

• 9

• 12

Which One is not a property of a Parallelogram?  

• Opposite Sides Congruent 

• Opposite Angles Congruent 

• Diagonals Bisect Each other 

• Diagonals Congruent 

Which of these are properties of a parallelogram?

• Both pairs of opposite sides are parallel

• Both pairs of opposite sides are congruent.

• Opposite angles are congruent.

• Consecutive angles are supplementary

• All 4 angles are congruent.

What shape has one pair of parallel sides and non parallel sides are congruent?

• Trapazoid

• Rhombus

• Rectangle

• Isosceles trapezoid

Match the following

• Rhombus

• A quadrilateral with exactly 1 pair of parallel sides

• Kite

• A parallelogram or kite with 4 congruent sides

• Trapezoid

• A quadrilateral with 2 pairs of parallel sides opposite each other

• Rectangle

• A quadrilateral with 2 pairs of adjacent sides that are congruent

• Parallelogram

• A parallelogram with 4 right angles

Parallelograms and trapezoids are different because a parallelogram has two pairs of parallel sides while a trapezoid has ​ (a)  

• only one set of parallel sides.

• all right angles.

• two sets of perpendicular sides

• obtuse and acute angles.

• all congruent sides

Which of these are properties of a rhombus?

• Consecutive angles are are supplementary.

• Opposite angles are congruent.

• All four angles are congruent.

• All four sides are congruent.

• Opposite sides are parallel.

Which quadrilateral has ONE pair of parallel sides?

• Parallelogram

• Rhombus

• Trapezoid

• Rectangle
