MATH 9 (3RD QUARTER)

What is the definition of a parallelogram?

• A quadrilateral with four right angles

• A quadrilateral with opposite sides parallel

• A quadrilateral with four congruent sides

• A quadrilateral with only one pair of parallel sides

Which of the following is always true about a parallelogram?

• Its diagonals are congruent

• Opposite angles are complementary

• Opposite sides are congruent

• All four angles are right angles

According to Theorem 5.1b, opposite angles of a parallelogram are:

• Complementary

• Congruent

• Supplementary

• Acute

Which theorem states that the diagonals of a parallelogram bisect each other?

• Theorem 5.1b

• Theorem 5.1d

• Theorem 5.2a

• Theorem 5.2c

If one pair of opposite sides of a quadrilateral is both congruent and parallel, then the quadrilateral is a:

• Trapezoid

• Rectangle

• Parallelogram

• Pentagon

What is true about consecutive angles in a parallelogram?

• They are congruent

• They are supplementary

• They are complementary

• They are perpendicular

Which of the following conditions is sufficient to prove a quadrilateral is a parallelogram?

• Only one pair of opposite angles is congruent

• The diagonals are perpendicular

• The diagonals bisect each other

• Only one pair of opposite sides is parallel

Which of the following shapes is always a parallelogram?

• Trapezoid

• Rectangle

• Kite

• Pentagon

A rectangle is a parallelogram that has:

• Four right angles

• Four congruent sides

• Two pairs of parallel sides but no right angles

• One pair of parallel sides

Theorem 5.2a states that if a parallelogram is a rectangle, then:

• Its diagonals are congruent

• Its diagonals are perpendicular

• Its diagonals bisect opposite angles

• Its opposite angles are supplementary
