When a rectangle is dilated, how do the perimeter and area of the rectangle change?

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol

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
