A shape with straight sides is called a polygon. But it can have 3 or 4 sides as well.
a triangle
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 has 4 vertices whereas a 3 sided shape has 3 vertices.
It is a polygon that has 3 or more sides
A shape with straight sides is called a polygon. But it can have 3 or 4 sides as well.
A shape with three sides is a triangle.
a triangle
A shape with four sides has more vertices because there are more points where edges (straight lines) meet than a 3-sided shape.
Shape has fewer than 6 sides
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 has 4 vertices whereas a 3 sided shape has 3 vertices.
A 4 sided shape which is a quadrilateral has more vertices than a 3 sided shape which is a triangle
It is a polygon that has 3 or more sides
If they are straight sides and the shape encloses a space then it is a polygon.
A triangle has three sides, so a hexagon (a shape with six sides) would have three more sides than a triangle.
A polygon is a shape with 3 or more sides, no openings, and no curved sides.
