New analogue and digital screen tools for interactive Macromedia Flash animations are offered. The analogue tools - a ruler and protractor - can be moved over the screen by parallel translation and rotation with accuracy high enough for teaching purposes. The digital tools allow to measure distances between two arbitrary points and angles between three points. Both the analogue and digital screen tools may be used with self-made as well as commercial images, for example 360 Color Images of Physical Phenomena (Ztek®Co). The measurements are illustrated by problems in optics, thermodynamics, and mechanics. Coauthor Dr. S.Ignatjeva/ University of Daugavpils (Latvia)
