Here you can configure application settings: 

There will be 2 lines on the screen. These two lines will have different lengths.

The first line is fixed (model). The second line with blue ends (small vertical lines) is of variable length.

Your task is to use the Drag and drop action to set the second line so that it is the same length as the fixed line.

In other words, you need to create two lines of equal (identical) length.

We emphasize that these 2 lines do not have to have the same slope, i.e. the angle between these two lines is completely irrelevant.

To change the length of the second line you need to click approximately exactly on the blue ending. Then start pulling the line (blue end) in the desired direction. To stop the Drag and drop action, release the mouse button.

As this is a demonstration task, both lines have equal lengths.

When you are done, click the button at the bottom right of the screen to display the next task.

To return to the previous task, click the button at the bottom left of the screen.

Descriptive statistics

The error is given as the ratio of the lengths of the two lines in percent. The error percentage is shown in red.
