The directrix is a line outside the parabola, while the focus is a single point inside its curve. The axis of symmetry shares the vertex's x or y value depending on whether it is a vertical or horizontal line and is perpendicular to the directrix.
A line that divides an object into two equal halves and produces a mirror-like reflection of each side of the object is known as an axis of symmetry. The word "symmetry" suggests harmony. Symmetry can be used in a variety of settings and circumstances.
An imaginary straight line known as the axis of symmetry is what divides a form into two identical halves or makes a shape symmetrical. A rectangle has two axes of symmetry, while a square has four.
