Instead of just drawing freehand, you place constraints on the geometry. You define that a line is tangent to a circle, or that two lines are perpendicular. The software then solves the geometric system based on these rules. This mimics the logic used in engineering CAD software but retains a mathematical focus.
The defining feature of the software is its ability to generate symbolic expressions. If you construct a ladder leaning against a wall, the software can generate an algebraic expression for the height of the ladder based on the angle and length, rather than just a decimal number. geometry expressions download
