Question:
Here is another proof of the Reflective Property.
(a) Figure 25 suggests that L is the unique line that intersects the ellipse only in the point P. Assuming this, prove that QF1 + QF2 > PF1 + PF2 for all points Q on the tangent line other than P.
(b) Use the Principle of Least Distance to prove that θ1 = θ2.
