Question

15. Suppose that PQ bisects ∠MPN. What conclusion can you make?

Answer 1

Answer:

The bisector of an angle is a ray that separates the angle  into two congruent angles.

As, PQ bisects $\angle MPN$

then,

$\angle MPQ \cong \angle QPN$

By the definition of congruent angle : An angle that have the same measure

$m \angle MPQ = m\angle QPN$

As you can also see in the figure as shown below;
