If 2 tangents to the parabola x = 2at, why =at^2 meet at right angles at Q and the normals at their points of contact meet at R, prove that QR is parallel to the axis of the parabola

I can't understand your question. Post the original question and your attempt at the solution.

Also, are you looking for a written proof, or just a drawn proof.

By the way, to anyone else that reads this, the system auto corrected the letter "y" to the word "why".
