Vertex of a parabola
The vertex of a parabola is the midpoint of the line segment joining the focus of the parabola to the directrix that is perpendicular to the directrix. This line is the line of symmetry of the parabola. If the parabola lies in a Cartesian coordinate system as the graph of the equation then this line is vertical and the vertex is the point at which the
-value of the graph is minimal (if
) or maximal (if
).
Vertex of an angle
