Rotation: Find the Centre Task 3

This example demonstrates the process of finding the center of rotation by rotating the vertices of a triangle. Core math concepts include rotation transformation, triangle properties, and coordinate geometry. Construction involves commands like Polygon and Rotate, using objects such as A, B, C, poly1, c, a, b, Centre, A', B', C', poly1', c', a', b', d. Suitable for high school students learning geometric transformations and coordinate geometry.
