This example demonstrates the rotation about the origin. Key mathematical concepts include rotation transformation and vectors. Using GeoGebra commands such as Polygon, Intersect, and Rotate, the rotated figure can be constructed. Suitable for middle school and above students or teachers.

GeoGebra Commands & Parameters

Polygon(A, B, C) → poly1, c, a, b
Intersect(xAxis, yAxis) → D
Rotate(A, α, D) → A'
Rotate(B, α, D) → B'
Rotate(C, α, D) → C'
Polygon(A', B', C') → poly1', c', a', b'
