Use the applet to discover the properties of the isosceles trapezoid.[br][br]By dragging any of the points, you may change the lengths of the nonparallel sides, BC and ED, so that they become congruent.[br][br]Check the remaining boxes one at a time in order to answer each question.[br][br]Observe the side lengths, angle measurements, and diagonals of the isosceles trapezoid. Then, write your answers in Task 2.
