Final answer:
If ray KM is a bisector of angle AKB, then K is the bisector of the ray and the vertex of the angle. ∠AKM and ∠BKM are equal since ray KM is a bisector.
Step-by-step explanation:
If ray KM is a bisector of ∠AKB, then K is the bisector of the ray and the vertex of the angle. We know that ∠AKM and ∠BKM are equal since ray KM is a bisector.
