Answer:

(1) C

(2) C

(3) 4

(4) False

Step-by-step explanation:

(1) If DF = FB, then point F is called the midpoint and segments DF and FB are congruent.

(2) If ray FA bisects angle EFB, then angles EFA and AFB are congruent.  If measure of angle EFA = 47 degrees, the measure of angle EFB = 47 degrees.

(3) If  DF = x+2,  FB = 2x+1 and DB = 15, then

DF + FB = DB

x+2+2x+1=15

3x+3=15

3x=15-3

3x=12

x=4

(4) If x=4, then

DF=4+2=6

FB=2·4+1=9

Since DF is not congruent to FB, F is not a midpoint. False
