Understanding Parallelograms

What is a defining characteristic of a parallelogram?

• All sides are equal

• Opposite sides are parallel

• All angles are right angles

• Diagonals are perpendicular

Which of the following is true about the opposite sides of a parallelogram?

• They are perpendicular

• They are congruent

• They are unequal

• They are bisected by diagonals

What is the sum of consecutive angles in a parallelogram?

• 90 degrees

• 180 degrees

• 360 degrees

• 270 degrees

What property of parallelograms is used to solve for a variable when opposite sides are given?

• Diagonals bisect each other

• Opposite sides are congruent

• Consecutive angles are supplementary

• Opposite sides are parallel

If one angle of a parallelogram is 60 degrees, what is the measure of its opposite angle?

• 90 degrees

• 60 degrees

• 180 degrees

• 120 degrees

In a parallelogram, if one angle is 120 degrees, what is the measure of its consecutive angle?

• 180 degrees

• 90 degrees

• 120 degrees

• 60 degrees

Which property is used to find missing angles in a parallelogram?

• Opposite sides are parallel

• Diagonals are equal

• Consecutive angles are supplementary

• All angles are right angles

How do diagonals behave in a parallelogram?

• They bisect each other

• They are perpendicular

• They do not intersect

• They are equal in length

If the diagonals of a parallelogram bisect each other, what can be said about the segments they form?

• They are unequal

• They are equal

• They form right angles

• They are parallel

What is the result when you set the expressions for bisected diagonals equal in a parallelogram?

• You find the length of the diagonals

• You solve for a variable

• You determine the area

• You find the perimeter
