Answer:
BI = BK
Step-by-step explanation:
A- Ab and Jk are not equal because the lengths are not specified
B- same as above; the lengths are not specified
C- We know that i and k are equal distances apart from B(due to the bisector given), so the distance to each of them from b must b equal
D- we do not know that aj and bj are the same, so we cannot assume ak and BI are equal
