FunctionTransformationGeometric Construction
This example demonstrates the concept of reflection transformation. Using GeoGebra commands such as Polygon, Line, and Mirror, you can create and explore the properties of reflection transformations. Key mathematical concepts include reflection transformation, functions, and geometric construction. Suitable for high school mathematics education and learning, particularly in coordinate geometry and transformation geometry.

GeoGebra Commands & Parameters

AI Drawing Prompt Reference

Draw a pentagon ABCDE, reflect it over line FG to get a new pentagon A'B'C'D'E'. Then, take two points H and I on the x-axis, and reflect pentagon ABCDE over line HI to get a new pentagon A'_1B'_1C'_1D'_1E'_1.
