Explanation

This is a sorting program.

The screen shows three boxes labelled all right angles, some right angles, no right angles, and eight different shapes.

The object is to classify the shapes according to their properties and place each in the correct box.

The user moves the mouse until it is over a shape - the cursor changes to a hand.

When the cursor has changed to a hand the user can drag the shape and place it in a box by clicking and holding the left mouse button.

Releasing the left mouse button will drop the shape.

In this screen shapes containing all right angles are placed correctly.

In this screen shapes containing some right angles have been correctly placed.

In this screen shapes containing no right angles have been correctly placed.

If the shape is placed in the wrong box it will pop back out.

This screen appears when the user has placed all the shapes correctly.

Clicking on this button repeats the activity.

This button should be clicked after each user has successfully completed the game.
