The applet below contains a quadrilateral that [b]ALWAYS remains a SQUARE. [br][/b]The purpose of this applet is to help you understand many of the geometric properties a square has. [br][br]Interact with this applet for a few minutes. Then, answer the questions that follow. [br]Be sure to move the two BIG white vertices around during your investigation!

Use this applet to investigate the answers to the following questions. [br]As you answer [i]each question[/i], be sure to drag the white points around to "put the square to the test", so to speak! [br][br]1) Is a square a parallelogram? If so, why? [br]2) Are opposite sides of a square congruent?[br]3) Are opposite angles of a square congruent?[br]4) Do the diagonals of a square bisect each other?[br]5) Does a diagonal of a square bisect a pair of opposite angles?[br]6) Are the diagonals of a square perpendicular?[br]7) Are the diagonals of a square congruent?[br]8) Does either diagonal of a square serve as a line of symmetry? If so, how many do?
