Parallelogram

Which of the following pairs of sides are congruent?

• BA and AR

• BR and EA

• AR and BE

• EB and BA

If measurement of line segment BA is 100cm, then what is the measurement of line segment ER?

• 50cm

• 100cm

• 150cm

• uncertain

∠B and ∠E are consecutive angles. Write the equation that describes the relationship between ∠B and ∠E.

• m∠B + m∠E = 90°

• m∠B = m∠E

• m∠B + m∠E = 180°

• m∠B + m∠E = 60°

True or False: Opposite sides of a parallelogram are congruent

• True

• False

True or False: Diagonals BR and EA are congruent

• True

• False

True or False: ∠B and ∠R are opposite angles, thus ∠B is congruent to ∠R
