[color=#000000]In the applet one diagonal of a parallelogram is shown.[br]The coordinates (x,y) of the endpoints of this diagonal are given. [br][br]In this task, determine 2 pairs of coordinates (x,y) for the endpoints of this parallelogram's other diagonal. [br]Construct this segment (and its respective endpoints) in the applet below. [br]Then, use the Polygon tool to construct the parallelogram.[br][br]Afterwards, use any of the tools this applet's limited toolbar to clearly show that the quadrilateral you've constructed is indeed a parallelogram.[/color]

[color=#0000ff]After successful completion of this activity, complete this same task again, this time replacing the word "parallelogram" (in the directions above) with the word "rectangle". [/color]
