The applet below contains a quadrilateral that ALWAYS remains an [color=#1e84cc][b]ISOSCELES TRAPEZOID[/b][/color]. [br][br]The purpose of this applet is to help you understand many of the geometric properties an [color=#1e84cc][b]ISOSCELES TRAPEZOID[/b][/color] has. [br][br]The questions you need to answer are displayed below this applet.

[color=#cc0000][b]Questions:[/b][/color][br][br]Use your observations from interacting with this applet to investigate the answers to the following questions:[br][br]1) Is an isosceles trapezoid a parallelogram?[br]2) Are opposite sides of an isosceles trapezoid congruent? If so, how many pairs?[br]3) Are opposite angles of an isosceles trapezoid congruent?[br]4) Do the diagonals of an isosceles trapezoid bisect EACH OTHER?[br]5) Does a diagonal of an isosceles trapezoid bisect a pair of opposite angles?[br]6) Are the diagonals of an isosceles trapezoid perpendicular? [br]7) Are the diagonals of an isosceles trapezoid congruent?[br]8) Does either diagonal of a isosceles trapezoid serve as a line of symmetry? If so, how many?
