The question is somewhat ambiguous.
If you mean a polygon in which the number of sides is not equal to the number of vertices, the answer is NO, there cannot be such a polygon.
If, however, the question is whether there is a polygon in which not all the sides are equal and not all the angles are equal, then the answer is YES, the vast majority of polygons are of this type.
It is classed as an irregular polygon when it has unequal sides.
Twelve. The number of sides and vertices in a polygon are always the same.
A polygon with three vertices and three sides is a triangle. A polygon with four vertices and four sides is a quadrilateral.
It will have 12 sides
A polygon has the same amount of vertices as it does sides, so it would have 7 vertices.
"What polygon has 5 unequal sides?" An irregular pentagon is a polygon that has 5 unequal sides.
It is classed as an irregular polygon when it has unequal sides.
Twelve. The number of sides and vertices in a polygon are always the same.
Fourteen. Each polygons has the same number of sides as it has vertices. Therefore, a polygon with 14 vertices must have 14 sides.
A polygon with 5 sides/vertices is called a pentagon.
12 sides, 12 angles, 12 vertices
A polygon with three vertices and three sides is a triangle. A polygon with four vertices and four sides is a quadrilateral.
19. sides=vertices
A polygon is a closed figure bounded by sides only. Triangle is the polygon of 3 sides and 3 vertices.
There is no specific name for a four-sided polygon with unequal sides.
It will have 12 sides
A polygon has the same amount of vertices as it does sides, so it would have 7 vertices.
