Dilate triangle STU with vertices S(-15, -3), T(-12, -15), and U(0, -9) by a scale factor of 1/3

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
