This example demonstrates the dynamic changes in triangles and their related vectors. Key mathematical concepts include triangles, vectors, and angles. Using GeoGebra commands such as Point, Segment, Rotate, Angle, etc., the construction process of triangles is visually illustrated. Suitable for high school mathematics education, particularly in coordinate geometry and vector topics.

AI Drawing Prompt Reference

Create a dynamic demonstration of triangles and vectors, showing two triangles and their related vectors, illustrating the construction process and angle changes. Start by drawing triangle ABC, then rotate point C around A by angle α to get B', connect AC and CB, draw a perpendicular line to AC at C named c_1, and a ray from A to B' named d, intersecting at B to complete triangle AB. Perform similar steps for the second triangle with points A_1 and C_1, rotating C_1 around A_1 by angle α to get B'_1, and showing dynamic changes with lines and vectors.
