Use the distance/length tool to find the length of the legs of the isosceles trapezoid. What appears to be true?[br][br]Drag the vertices to make sure this is always true.
Use the segment tool to draw in the diagonals of the isosceles trapezoid. Use the distance tool to find the length of each diagonal. What appears to be true?[br][br]Drag the vertices to make sure this is always true.
Use the angle tool to find the measure of each interior angle. What is the relationship between the base angles (angles that share the same parallel side).[br][br]Drag the vertices to make sure this is always true.
