The applet below contains a quadrilateral that ALWAYS remains a rectangle. The purpose of this applet is to help you understand many of the geometric properties a rectangle has. The questions you need to answer are displayed below this applet.

Use the tools GeoGebra within this applet to investigate the answers to the following questions:
1) Is a rectangle a parallelogram?
2) Are opposite sides of a rectangle congruent?
3) Are opposite angles of a rectangle congruent?
4) Do the diagonals of a rectangle bisect each other?
5) Does a diagonal of a rectangle bisect a pair of opposite angles?
6) Are the diagonals of a rectangle perpendicular?
7) Are the diagonals of a rectangle congruent?
8) Does either diagonal of a rectangle serve as a line of symmetry? If so, how many?
