A Quick Start

The following two sections will guide you through large parts of Cinderella's functions. After working through the tutorials you should be able to use Cinderella. You can look up other functions in the reference part of this manual. Most of the functions described there follow patterns that are explained in the tutorials.

Here are a few general instructions on how to use these tutorials.

• Read the texts carefully. When you come to a new section of the tutorial read it first completely. Then you should read it again, while you perform the described actions.
• Follow the instructions exactly. The tutorials ask you to do constructions in a certain order. If you do not stick to the same order then the labelling of your elements will be different from that in the tutorial.
• If you made a mistake there is always the chance to undo the last step by pressing the "Undo" button in the tool bar. You can undo as many steps as you want.
• The pictures in the tutorials are intentionally screenshots, and not high-quality printouts. It should be easy to match these drawings with the actual situation on your screen.

Each tutorial focuses on a certain topic. The information provided by the tutorial text becomes less and less detailed. We assume that it is helpful in the very beginning to be told precisely what to do. The more advanced you get the more freedom you will have to do the operations.

• Pappos' Theorem
  This tutorial introduces you to the basic construction principles of Cinderella. You will learn how to do a simple construction.
• Three Bar Linkage
  Here you will learn how to use the animation features of Cinderella. You will also see how to produce geometric loci.
