What Is a Vertex in Geometry?
Vertex is a corner of a shape and it is one of the most basic topics in geometry. It is a crucial part of the learning process and it is essential to master this concept early in life. Help your kids learn about what is a vertex with impactful resources from SplashLearn.

What Is a Vertex?
In mathematics, a vertex is a point where two lines meet, or where two line segments intersect. It can also refer to the top or apex of a shape such as a triangle or a pyramid.
What is a Vertex in 2D and 3D?
In math, a vertex is a point on a shape where two straight lines or edges intersect. This can be a plane shape such as a rectangle or a solid shape such as a cube.
A geometric shape usually has a vertex, or it can have multiple vertices. This is common in 3D shapes such as cubes and cuboids.
How Many Vertices Does a Square Have?
A square has four vertices, which are its corners. It can also have more vertices, like the vertices of a pentagon or a hexagon.
What is the Vertex Angle?
The vertex angle is a key element of angles. When two lines or rays meet at a vertex, they form an angle. This is why angles have a different name for their vertex than their point on each side.
What is the Vertex of a Parabola?
The vertex of a parabola is the point where a line that goes from one point to another ends. This can be an important mathematical concept to learn because it is used in many equations.
What Are the Properties of 2D and 3D Shapes?
Every 2D and 3D shape has vertices, faces and edges. The vertices are the points where straight lines or edges intersect, and the faces are the flat surfaces that meet at those points.
Edges are the line segments that join one vertex to another. They can be straight or curved. They can be seen and hidden, as in the case of a cube’s edges.
What are the vertices, faces and edges of a triangular prism?
A triangular prism has 6 square faces, 12 straight edges and 6 vertices. This is a very simple example of how these different properties of shapes work together.
What are the vertices, edges and faces of a hexahedron?
A hexahedron has 8 square faces, 12 straight edges and 8 vertices. This is a perfect example of how edges and vertices combine to describe different 2D and 3D shapes.
What are the vertices, angles and faces of a tetrahedron?
A tetrahedron has 4 vertices, or edges. It can have more vertices, like the edges of a pentagon or a diamond.
What are the vertices, sides and angles of a rectangular shape?
A rectangular shape has 4 sides and 4 vertices. This is a good example of how to combine these different aspects of a shape to give a complete answer.
