3. This is easy as we know that this line is perpendicular to the base. The point B should
be somewhere on this line l.
4. To locate the point B, we can draw an arc on the line l.
5. Construct perpendiculars to DC and BC passing through D and B, respectively. The
point where these lines intersect is the fourth point A.
Check if ABCD is indeed a rectangle satisfying properties:
The opposite sides are equal in length.
All the angles are 90°.
