Whether reflecting sound or waves, parabolic reflectors rely on the properties of tangents to conic sections. Let's fully dissect the underlying geometric phenomenon exploited in the making of antennas of every kind.

Behind its sleek appearance, the parabola brims with fascinating properties. Thus, the study of its tangents reveals remarkable angular properties and offers a playground of astonishing richness, where classical geometry meets luminous reflections.

Anyone may come across a polynomial along the way. Here's the proof...

A common exercise in the days of descriptive geometry was to construct a point on a curve and its tangent. Following the ellipse, here is a short survival guide offering a handful of constructions for solving the same problem for the parabola.

Equidistance is introduced very early in geometry. Perpendicular and angle bisectors are the simplest examples. Let us go further and consider points equidistant from a line and a circle, from two circles, or even from two more general curves. How far can we take this?
