Vertex – Definition and Examples 

Vertex – Latin word Vertex meaning, “highest point”.

What is Vertex?

Vertex is a point where two or more rays or line segments are meet.

When two rays or line segments meet, simply it is a corner, they form an angle.

Definition:

A vertex is a point on a polygon, where two line segments or rays are meet.

When two rays or lines meet at a point they form an angle. So, we can say that the meeting of two line segments or rays forms a vertex.

When two lines meet at a point to form a vertex, they also form an interior angle.

Vertex of Two Dimensional Shapes

A two-dimensional or 2D figure is a figure or shape that we can represent in two dimensions.

Example: 2D shapes are square, rectangle, triangle.

The vertex of 2D figure is the point of intersection of two sides of the shape. The two sides of the shape or figure meet to form an angle and a vertex is formed.

In 2D and 3D shapes or figures V represents the vertices of each figure.

Example: A triangle has three corners, which are its three vertices. The corners of the polygons are vertices.

Example: ABCD is a square, A, B, C, and D are its four Vertices.

A hexagon has six vertices.

A figure or object that does not have any sides or edges does not have any vertex.

Example: circle, sphere, cylinder do not have any vertices.

Some two dimensional shapes do not contain any vertices for example circle and ovals have no corners.

Vertex of Two Dimensional Shapes

A three-dimensional or 3D figure is a figure or object that is represented in three-dimensional space.

A 3D figure or a solid shape has all three attributes, length, width and height.

The vertex of a 3D figure is the point of intersection of two sides of the figure.

In 3D figure multiple sides and edges can intersect at one point.
