FunctionTrigonometryCoordinate GeometryGeometric Construction
This example demonstrates the calculation and visualization of intersection points between polygons, circles, and linear regression lines. Core math concepts include coordinate geometry, similar triangles, function graphs, and linear regression. Construction involves commands like Polygon, Mirror, Circle, Intersect, with sliders to control transformations and compute intersections like A', B', C'. Suitable for high school mathematics education, emphasizing the integration of geometric transformations and data analysis.

AI Drawing Prompt Reference

Draw a triangle defined by three points, then reflect each vertex across three lines to obtain three new vertices, and connect these new vertices to form another triangle. Next, reflect the original triangle's vertices across two other lines to get two sets of new vertices, and connect them to form two more triangles. Finally, draw three circles with centers at pairs of the original triangle's vertices and one of the new triangles' vertices, and find the intersection points of two of the circles.
