GeoC provides quick solutions for 8 types and many variations of line and circle calculations and offers immediate visual verification by drawing a picture of the calculation using the calculated results. The 8 are:
 Intersection of 2 circles and resulting areas.
 Intersection of a line and a circle and resulting areas.
 Circle tangent to a line and a circle.
 Circle tangent to 2 circles.
 Circle tangent to 2 lines.
 Line tangent to 2 circles.
 Circle defined by 3 points.
 Small circles aligned with a big circle.

FEATURES:
 Precise double byte accuracy.
 All the possible roots at one time. The different roots are selectable and viewable.
 The calculators solve each problem by analysis using algebraic rather than geometric methods. The data and results are in the users coordinate system from maps or drawings.
 Methods of analysis are described in help.
 Accepts expressions and constants as input.
