Definition
The point at which the arms of an angle meet is known as the vertex of that angle.
Historical Note
While the term is used throughout Euclid's The Elements, the concept of the vertex of an angle is never formally defined there.
Linguistic Note
The plural of vertex is vertices.
The word vertex is Latin for peak, from which the irregular plural form.
