We are given that l bisects SU. By the Segment Addition Postulate,​ (a)   . By the definition of ​ (b)   , ST ≅ TU. Congruent segments have equal length, so ​ (c)   . Substituting this into ST + TU = SU gives ST = 1 2 SU.

• ST+TU=SU

• Segment Bisector

• ST=TU

• ST+SU=TU

• Segment Divider

• ST=2SU
