AI Drawing Prompt Reference

Create a dynamic geometry illustration featuring a cone, a cuboid, and a hyperbola, demonstrating the Pythagorean theorem in 3D space. Start with a circle and a radius, place a point on the circle, draw a ray, and construct perpendicular lines to form multiple intersections. Use rotations and angles to create two circular sectors, then apply scaling and translation to move these sectors along vectors, creating animation. Include various points, segments, angles, and vectors, all controlled by sliders to show the relationship between solid and plane geometry.
