If j = h and k = m, then which expression represents the value of g? triangle ACB, point E is on segment AC between points A and C and point D is on segment BC between points B and C, creating segment ED, CE equals h, EA equals j, CD equals k, DB equals m, ED equals g, and AB equals f

g equals f over 2
g = 2f
g equals j over h
g equals k over m
