The large drawing at the top of the screen shows the parts of the circle. All these drawings are arranged according to a certain rule. One drawing is missing. This drawing is marked with a "?".
The bottom of the screen offers solutions to the task. Click on the drawing below that you think is the solution to the task.
If you think that none of the images is correct, do not click on any of the images, just click on the button for the next task (bottom right).
To return to the previous task, click on the button at the bottom of the screen (bottom left). You can then cancel your choice by clicking the same or another image again.
The correct choice has a different background color than the other images (if it exists).
Your results will be displayed at the end of the task.
