[color=#cc0000][b]Students: [/b][/color][br][br]The applet below contains a quadrilateral that [color=#1e84cc][b]ALWAYS remains an ISOSCELES TRAPEZOID.[/b][/color][br][br]Be sure to move the [color=#1e84cc][b]BIG BLUE VERTICES[/b][/color] of this [color=#1e84cc][b]ISOSCELES TRAPEZOID[/b][/color] around as you answer each investigation question!
Measure the base angles using the measuring tool, then manipulate the applet to make different isosceles trapezoids.[br]1. What can you conclude about the measure of the base angles of the isosceles trapezoid?[br]2. What can you conclude about the opposite angles of the isosceles trapezoid?[br]3. What can you conclude about the consecutive angles along a leg of the isosceles trapezoid?[br]4. Does you conclusions apply to any trapezoid (not isosceles)?
Using the measuring tool, measure the length of the diagonals. Manipulate the applet to make different isosceles trapezoids.[br]1. What can you conclude about the diagonals?
