Develop a deeper understanding of the definition of parabolas, ellipses, and hyperbolas with paper folding. Discover that what looks like each conic section is really the "envelope" of tangent lines. Find where the loci of points actually are, mimic the same actions on the TI-NSpire, and compare and contrast the ellipse with the hyperbola.
