Use the UnMessUpAble Isosceles Trapezoid ABCD for this investigation.[br][br]1. Measure the diagonals of the isosceles trapezoid. Move the vertices around. [br]2. Write a conjecture about the diagonals of an isosceles trapezoid.[br]3.Measure all the angles of the trapezoid. Move the vertices around. [br]4. Write a conjecture about the base angles of an isosceles trapezoid.
