Explanation of the Properties of Rectangles
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?
