What is the answer to the problem? 10 points :)

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m

What’s the range cuz i can’t find it?
