Two rectangles are called congruent rectangles if the corresponding adjacent sides are equal. As you may recall, congruent polygons have the exact same size and are a perfect match because all corresponding parts are congruent (equal). We do not need to check the angles as all angles in a rectangle are 90 degrees. Scale factor = larger length / shorter length. Scale Factor = Perimeter of larger polygon / Perimeter of smaller polygon Variables.
