In this applet we study the shapes that can formed by two absolute value functions.[br][br]Use the white dots to position the vertices of the absolute value functions.[br]Use the blue and green dots to determine the slopes of the functions on either side of the vertex.[br][br]What absolute value functions are the blue and green lines?[br]Where do they intersect?[br]What is area of the quadrilateral formed?[br][br]How can you make this area into a rectangle? [br]a kite? a parallelogram? a square? a rhombus?
