Properties of Parallelograms

A parallelogram is a geometric figure with opposite sides that are parallel and equal in length. The opposite angles are also equal, and the sum of the angles between parallel lines is 180 degrees.

What is the primary characteristic of a parallelogram?

• All sides are equal

• Opposite sides are parallel

• All angles are right angles

• It has four sides

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

• Adjacent sides are equal

• All sides are different

• Opposite sides are equal

• Only one pair of sides is parallel

What can be said about the opposite sides of a parallelogram?

• They are curved

• They are unequal

• They are perpendicular

• They are parallel

In a parallelogram, how do the lengths of opposite sides compare?

• They are double

• They are unrelated

• They are half

• They are equal

What is true about the angles in a parallelogram?

• Opposite angles are equal

• Adjacent angles are equal

• All angles are obtuse

• All angles are acute

How do the opposite angles in a parallelogram relate to each other?

• They are complementary

• They are supplementary

• They are different

• They are equal

If one angle in a parallelogram is 70 degrees, what is the measure of its opposite angle?

• 180 degrees

• 110 degrees

• 70 degrees

• 90 degrees

Which of the following best describes the angles in a parallelogram?

What is the sum of the angles between parallel lines in a parallelogram?

• 90 degrees

• 180 degrees

• 360 degrees

• 270 degrees

Which statement is true about the angles formed between the parallel sides of a parallelogram?

• They are always right angles

• They sum up to 180 degrees
