Prove lo bisects angle mln and identify which given statement is unnecessary.

Given:

LM = LN, KM = KN, KO bisects angle MKN

What we want to prove:

LO bisects angle MLN

Proof:

Statement 1: KM = KN

Reason 1: Given

Statement 2: KO bisects angle MKN

Reason 2: Given

Statement 3: Angle MKO = Angle NKO

Reason: Definition of angle bisection

Statement 4: KO = KO

Reason 4: Reflexive property of congruence

Statement 5: Triangle MKO = Triangle NKO

Reason 5: SAS postulate

note: this combines statements 1, 3, and 4 (for the "S", "A", and "S" in that order)

Statement 6: MO = ON

Reason 6: CPCTC

note: CPCTC stands for "corresponding parts of congruent triangles are congruent"

Statement 7: Angle KOM = Angle KON

Reason: CPCTC

Statement 8: OL = OL

Reason 8: Reflexive property of congruence

Statement 9: Triangle MOL = Triangle NOL

Reason 9: SAS postulate

note: used statements 6, 7, 8 for the "S", "A", "S" in that order

Statement 10: Angle MLO = Angle NLO

Reason 10: CPCTC

Statement 11: LO bisects angle MLN

Reason 11: Definition of angle bisection

That concludes the proof. We did not use the statement "LM = LN", so it is unnecessary.
