##### Here is another proof of the Reflective Property. (a) Figure 25 suggests that $\mathcal{L}$ is the unique line that intersects the ellipse only in the point $P$. Assuming this, prove that $Q F_{1}+Q F_{2}>$ $P F_{1}+P F_{2}$ for all points $Q$ on the tangent line other than $P$. (b) Use the Principle of Least Distance (Example 6 in Section 4.7) to prove that $\theta_{1}=\theta_{2}$.
