Parabola Reflection Property
Adapted from Mathematics Magazine June 1991, p. 175

Given: the parabola y2 = 4px, F is the focus, QA is tangent to y2 = 4px at Q.
Prove: at any point Q, angle 1 = angle 3


Elliptical Reflection Property
Given: an Ellipse
To Show that a line drawn form one focus to the ellipse would reflect to the other focus
