This type of shape generator is different to the others. In practice session 1 of this module you worked with the option Jigsaw with curved unions, which has the same options and follows the same procedure as those with rectangular and triangular fitting edges. The option Cuts is completely different. Here you will work with some basic tools. Once you have selected the option Cuts you will see that the image in the panel is no longer divided into pieces. You have to create the pieces of the puzzle from the window Properties of the shape generator. Click on the button which is to the right of the menu to access Select type of shape generator. This window contains the tools for cutting the image into shapes which will become the pieces of the puzzle.
Select the tool to draw circles . Draw a circle which corresponds to the image. Once done, you can adjust the size by dragging the mouse from the points at the outer edge. You can also move it by dragging on the mouse. |
Once you have drawn the first piece, you will see that on the right, number 0 appears. Each time you draw a piece, a number will appear. To work with the pieces later you must select them from here. The chosen cut will be blue and the points that mark the limits will be marked with larger squares. Choose the tool for rectangles and draw a cut that coincides with one of the square pieces and another with a rectangular one. Adjust them in the same way as with the circle. Select the tool for polygons . Trace the form of one of the triangular pieces. Adjust as before. With the same tool make a cut which has the shape of a quarter of a circle. Draw a triangle. Select the side which should be round and click on the tool which will help you to convert the straight line into an arc. Drag the black square which has appeared on the straight line until you have the required shape.
