This example demonstrates reflection transformation. By applying the reflection operation, you can observe the symmetric changes of points, line segments, and polygons across a mirror axis. Key mathematical concepts include reflection transformation and geometric transformations. The example uses commands like Polygon, Segment, and Mirror to construct a quadrilateral and its reflected image. Suitable for students at the middle school level and above to learn about geometric transformations.

GeoGebra Commands & Parameters

AI Drawing Prompt Reference

Draw a hexagon with six vertices, then draw a straight line as the axis of symmetry. Reflect each vertex of the hexagon across this line to obtain six corresponding mirror points. Connect these mirror points in order to form a second hexagon that is the mirror image of the original across the line. The two hexagons are identical in shape and size, located on opposite sides of the axis, with corresponding vertices connected by lines perpendicular to and bisected by the axis. This illustrates the reflection transformation of a planar figure.
