 - Insert, using the **push** button exactly 2 vertices. Then, navigate to **Tools > Rasterize line with...** and choose any algorithm.
 
 **How to apply one or more transformations in a 2D polygon?**
 
 - First, you should know that you must insert at least 3 vertices through the **'push' button**, in the main screen. After this, you can render your polygon clicking in **Tools > Render**, or pressing **F4 key** shortcut. 
 
-- With you polygon rendered, now you can apply any of one transformations available in the **2D Transformations** tab. You can check the selected transformation an set the necessary parameters, then you should click in **Tools > Update** or press **F5 key** to apply and see the output.
