Rectangle Construction

Explore the geometric properties of a rectangle
    Summarize the properties of a rectangle before you start your actual construction.  Hint: If you are not familiar with the construction steps necessary for a rectangle construction, you might want to explore the applet below. Just use the buttons of the Navigation Bar in order to replay the construction steps. 
    Task
    Construct a rectangle that passes the Drag Test by following the construction steps provided below.
    Try it yourself...
    Construction steps
    1.Create segment AB.5.Create a perpendicular line to segment AB through point A.
    2.Create a perpendicular line to segment AB through point B.6.Construct intersection point D.
    3.Create a new point C on the perpendicular line.7.Create the polygon ABCD. Hint: To close the polygon click on the first vertex again.
    4.Construct a parallel line to segment AB through point C.8.Apply the Drag Test to check if the construction is correct.
    Hint: You might want to save your construction using the File menu.
