I see that you have uploaded an image of a math problem in Vietnamese. Let me analyze the contents and provide an explanation for the problem.

It seems to be a geometry problem involving a triangle $ABC$ with certain geometric constructions. The problem involves various steps, such as:

Constructing specific points and lines, including $M$ and $N$ , which seem to be related to perpendicular bisectors and other geometric properties.
Proving the equality of angles or distances.
Demonstrating that certain triangles are congruent or equal in some way.

I can help you work through this. Would you like me to go through the steps of solving the problem? Or would you like to focus on a specific part?
