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 shape with 7 sides.
A shape with four sides has more vertices because there are more points where edges (straight lines) meet than a 3-sided shape.
A 4 sided shape which is a quadrilateral has more vertices than a 3 sided shape which is a triangle
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).
A 4 sided shape has 4 vertices whereas a 3 sided shape has 3 vertices.
Shape has fewer than 6 sides
any closed shape with 4 sides or more sides. The question does not specify only four vertices!
The number of vertices does not determine the number of faces. If the shape with 6 vertices was a quadrilateral based bipyramid, it would have 8 faces. A hexagonal based pyramid has 7 vertices and 7 faces. So more vertices does not necessarily imply more faces.
Polygons of 6 or more sides have more than 5 vertices such as an octagon which has 8 vertices
Yes. Two triangle touching corner-to-corner. There would be six sides, but only 5 vertices because one vertex is shared.
Four sides ⇒ it is a tetrahedron. More commonly, it is called a triangular pyramid.
