CircleTransformationGeometric Construction
① This GeoGebra example demonstrates geometric reflection transformation, showing symmetry of figures across a line or point; ② Core concepts include reflection, congruence, and the role of circles and arcs in construction; ③ Constructed using Circle, Point, Segment, and CircleArc commands with defined points A, B, C, etc.; ④ Suitable for middle to high school geometry education, helping students intuitively understand reflection properties and construction methods.
