Question

select the definition, property, or postulate that is represented by the diagram. midpoint acute angle angle bisector vertical angles

Explanation:

• Midpoint: Relates to a point dividing a segment into two equal parts, not angles. So this is incorrect.
• Acute angle: An angle less than 90 degrees, the diagram shows a line splitting an angle, not just an angle's measure. Incorrect.
• Angle bisector: A ray that divides an angle into two congruent angles. The diagram has ray \( MP \) splitting \( \angle LMN \) into two equal - angled parts (indicated by the arc marks), so this matches.
• Vertical angles: Angles opposite each other when two lines intersect, not shown here. Incorrect.

Answer:

C. angle bisector
