A vertex is where two or more line segments meet. A corner.

Plural of vertex is vertices (pronounced “ver-tiss-ease”).

A vertical X (vertex) shows the X marking the high point. But in maths it’s even more precise. It is where there are corners, and or, where two or more lines meet.

A pentagon has five vertices

 

Example 2

A square has four corners but these are four vertices too.

 

Example 3

Where two lines meet is a vertex.

A parabola can be thought of as two curves meeting, that is why mathematicians still call this a vertex. This can be the high point or low point of the graph.
