There are many shapes that have fewer than 3 vertices like the circle, hyperbola, semi circle, and many others.
However if you are only talking about polygons then there is no actual shape with fewer than 3 vertices that you can find in a real life situation but they do have names for these shapes. A 2-sided polygon is known as a digon. A 1-sided polygon is known as a monogon. These shapes only exist in theory however and not in real life.
A shape with four sides has four vertices and a shape with three sides has three vertices, so a shape with four sides has more vertices than a shape with three sides.
A triangle for example has 3 vertices.
-3
a triangle has 3 sides, and a circle has 1
Definately a triangle
Shape has fewer than 6 sides
A pentagon.
It is a sphere, a cylinder and a cone that have less than 3 vertices!
A shape with four sides has four vertices and a shape with three sides has three vertices, so a shape with four sides has more vertices than a shape with three sides.
A 4 sided shape which is a quadrilateral has more vertices than a 3 sided shape which is a triangle
There is no shape with 4 faces and 3 vertices
A shape with four sides has more vertices because there are more points where edges (straight lines) meet than a 3-sided shape.
A triangle has 3 vertices.
The description given can be applicable to some 4 sided quadrilaterals like a square or a rectangle.
A triangle for example has 3 vertices.
A 4 sided shape has 4 vertices whereas a 3 sided shape has 3 vertices.
Assuming that each vertex is used to connect exactly two sides, all two-dimensional shapes will have the same number of sides as vertices. So a shape with 4 sides will have 4 vertices and a shape with 3 sides will have 3 vertices. Think of a square (4 sides, 4 vertices) and a triangle (3 sides, 3 vertices).
