Pick's Theorem Explorer

Drag the vertices of the quadrilateral to different pegs on the virtual geoboard. Click on the Capture Data button to populate the table with the number of boundary points, interior points, and quadrilateral area. Use the collected data to deduce Pick's formula for the area of the quadrilateral based upon the boundary points and interior points.[br]
