There are multiple uses of the word **vertex** in mathematics, including uses in graph theory and multiple uses in geometry.

## Vertex of a parabola

The **vertex** of a parabola is the point which, if a vertical line is placed over it, divides the parabola into two equal mirror images.

## Vertex of an angle

See angle.

## Vertex of a polygon or polyhedron

See polygon.
