How to find the distance between lines using the Pythagorean Formula

# Deriving the Equation of a Parabola in General

Watch this video to get a better sense for how a parabola is defined geometrically, and how we can use the distance formula to help us find the equation of the parabola based on that definition. Remember, we need two distances to be the same for any point on the parabola. The distance from the point on the parabola to the focus must be the SAME as the distance from the point on the parabola to the directrix.
