Coordinates and Linear Equations
This example dynamically demonstrates the coordinate changes of a boat, showcasing the interaction of geometric figures like rotation, circle, and scalene triangles. Core math concepts include rotation, circle, scalene triangle, arithmetic, and interest calculation. It utilizes commands such as Random, Circle, Ray, OrthogonalLine, Intersect, CircumcircleArc, Midpoint, Sequence, If, Segment, Polygon, Line, Rotate, Mod, and Point in GeoGebra for construction. Suitable for middle school and above students learning coordinate geometry, geometric transformations, and data analysis.
