The normal at any point on the ellipse bisects the angle made by the point with the two foci of the ellipse. What is this property called? Correct Answer Focus-to-Focus property

Let a point ‘P’ be on an ellipse, and F1 and F2 are the focus of the ellipse. Then the normal at P bisects the angle between the PF1 and PF2. This property of the ellipse is called a focus-to-focus property of the ellipse.
