VectorCoordinate GeometryTransformation
This example demonstrates translations on a grid. Key mathematical concepts include translation and vector. Using commands like Polygon, Textfield, Translate, Segment, Point, Vector, the effect of translation can be constructed. Suitable for middle school and above students to learn geometric transformations.
