Instructions for Use
Touch Pegs prompts students to investigate relationships between triangles and parallelograms.
To use Touch Pegs, select a circle by holding the mouse button down, and drag it to any location on the gird. Release the circle to anchor it. A red node appears at the top of the circle. Click on any part of the circle and drag it in any direction. It will stretch much like a rubber band. Secure the band to any points on the grid. Make squares, triangles, rectangles and many geometrical shapes.
Click on the circle again to add other bands. To colour the area in the shape, click first on the shape and then on the colour buttons to the left. To release a node, hold the Ctrl key down and click on the node. Click on the 'Measure' button to determine the area and perimeter of the shape. Click on the 'Clear' button to start the exercise over again.
