Final answer:
PN bisects MO and is perpendicular to it, forming right angles. This can be explained using the definition of a triangle.
Step-by-step explanation:
In the given question, it is stated that PN bisects MO and PN is perpendicular to MO. From these statements, we can understand that PN divides the line segment MO into two equal parts and forms right angles with it. This can be explained using the definition of a triangle, which states that the sum of the angles in a triangle is 180 degrees. Therefore, the angle MON is 90 degrees, and since PN bisects MO, the angles NOP and NOP are also 90 degrees.
