Instructions for Use
Symmetrical Shapes allows your child to construct 2-D shapes with one line of symmetry.
To use Constructing Symmetrical Shapes, on the "object" side of the grid, click squares to form half of a shape. Be sure to connect your shape to the line of symmetry. Click on the grid button to show the reflected image of your shape. The reflected image makes up the other half of your shape.
To change the direction of the line of symmetry, click the star button. The line of symmetry can be horizontal, vertical, or diagonal.
