Here you can configure application settings: 

There will be 3 circles (dots, points) on the screen that form a triangle.

2 black circles are fixed.

The blue circle is movable.

Your task is to use the Drag and drop action to move the blue circle to a position that is equidistant from the 2 fixed black circles. In other words, you need to create an equilateral triangle from these 3 points.

To activate Drag and drop click exactly on the blue circle and start dragging it in the desired direction.

As this is a demonstration task, the blue circle is always placed in the optimal position so that all 3 circles form an equilateral triangle.

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

Perimeter of a triangle is the sum of all its three sides. The error is shown as the deviation of the measured perimeter of the triangle from the perimeter of the optimal equilateral triangle. Unit: percentages. The error percentage is shown in red. The minimum possible error is 0%.
