Construction can be traced 'step-by-step'.
Only that the language is very simple and can be used by a person not familiar with other computer languages. Writing source files is like programming. For example: the word 'circle' will appear in a yellow color, but an incorrect word 'ccircle' will appear in a white color. All main commands are enlightened with yellow color, when they are written correctly. However 'Literka' provided a special editor for 'Ruler and Compass'.
Construction text (source files) can be written with any text editor. Using of it is straightforward - instead of drawing - just write. Program provides a very simple and understandable geometrical-computer's language. The second way of using of program 'Ruler and Compass' is to write a text for geometrical constructions. A computer names all figures and names are written on a screen. A computer will find all intersections and this makes the difference with ordinary graphical program - it allows much higher precision. Pictures of circles, lines, and segments may be drawn with a mouse. The difference is that everything is done on computer's screen, not on a paper. "On screen" constructions allow to construct geometrical figures the way as they are constructed with ruler and compass and only these constructions are possible for "on screen" constructions. There are two ways of using of this program.
COMPASS FOR GEOMETRY CLASS SOFTWARE
Ruler and Compass is a math software which was designed for helping the students of elementary or secondary schools.
