Explore! From 3D to 2D: Parabola as Projection of a Circle

This activity shows how we can obtain a parabola by projecting a circle on a plane perpendicular to it. Toolbar Image Move the vertices of the base of the cube to change its size. Move point P along the circle, or start the animation, to generate the locus of point P', which is the projection of P on the plane perpendicular to the circle.
