Quadrilaterals are shapes with four straight lines. But depending on how those straight lines intersect one another, gives rise to special situations and special quadrilaterals. For example, a square is a quadrilateral with sides all the same length and any two sides intersect at right angles. As a result, opposite sides of a quadrilateral are parallel.

When we are faced with a quadratic that is not “nice” to factor we need to find a way to factor it. This is where the quadratic formula comes in. The discriminant is a value that can be calculated for each quadratic equation.
