Frequently Asked Questions

Trova risposte rapide

How is the angle calculated?

The angle is computed using the arctangent function (Math.atan2) with the difference in y and x coordinates: angle = atan2(y2 - y1, x2 - x1).

What coordinate system is used?

This tool uses a standard 2D Cartesian coordinate system with x (horizontal) and y (vertical) axes.

Can I use negative coordinates?

Yes, both positive and negative coordinates are supported for accurate angle calculation in all quadrants.

Is this tool free to use?

Yes, this angle calculator is completely free with no limits or registration required.
