In the diagram, \angle NLO = \angle MLO, \angle NMO = \angle LMO and \angle MNO = \angle LNO. (LO, MO and NO are called the angle bisectors of \triangle LMN.) If \angle LNM = 2\theta, what is the measure of angle LOM?

Step 1
Similarly, since MO is an angle bisector of LMN, we know that ZNMO = ZLMO. And since NO is an angle bisector of LMN, we know that ZMNO = ZLNO. Show more…
