point E is the midpoint of ab and point f is the midpoint of CD

AB is bisected by CD (TRUE). This is True because E is the midpoint between A and B and CD passes through ECD is bisected by AB (FALSE) CD is bisected by point F and not ABAE = 1/2 * AB (TRUE) since E is the midpoint of AB , E divides AB into two equal halvesEF = 1/2 * ED (FALSE) The true statement would have been CF = 1/2* CDFD = EB (FALSE) sinc we do not know if CD and AB are of the same lengthsCE + EF = ED (TRUE) since F is the midpoint the sum of CE and EF is equal to ED
