! 1 Fill in the missing statement and reason of the proof below. Given: ABCD is a parallelogram, E is the midpoint of AB and F is the midpoint of DC. Prove: DE FB. Step 1 N 3 6 2 7 Statement ABCD is a parallelogram E is the midpoint of AB F is the midpoint of DC → DC DF = DC AB EB = ¦ AB DF EB Type of Statement DC AB #m DFBE is a parallelogram с $ 4 Reason Given Opposite sides of a parallelogram are congruent When a midpoint divides a segment into two parts, each part is half the length of the whole segment When a midpoint divides a segment into two parts, each part is half the length of the whole segment Segments that are half the lengths of congruent segments are congruent Opposite sides of a parallelogram are parallel DFBE is a parallelogram because it is a quadrilateral with one pair of opposite sides parallel and congruent % 5 DELL Oll < 10 6 & 7 3 8
