That would make a circle. Only when you zoom in would you see that it is made of tiny straight lines.
You may be fishing for "polygon", but I thinksomething in your description has gang aglae.
If the figure is a polygon ... with sides made of straight line segments ... then the perimeter is the sum of the lengths of all the sides. If part or all of the figure's boundary consists of curves, the perimeter is still the distance all around the figure, but you may need special formulas to find the lengths of the curved sections.
A hexagon is a plane (2-dimensional) figure with 1 face, 6 vertices and 6 sides (which may be called edges).
Not always because a quadrilateral is any 4 sided shape.
A polygon is a closed figure on a plane. A regular polygon has all the sides of equal length and the included angles the same. Known by their number of their sides. square, triangle, pentagon. octagon, nonagon etc ... . One may also have a polygonal prism, a solid figure with 3, 4, 5 ... equal sides, and an extended height.
a figure that has 10 sides* * * * *It is a plane figure, bounded by ten straightlines, which meet in pairs at ten vertices.
it may be a parallelogram or a kite both have opposite sides equal
no, but an eight sided figure you could use is an octagon. a figure 8 may be a figure and closed but, it has no sides and no line segments.
any regular polygon with an odd number of sides... triangle, pentagon, septegon, etc. a quadrillateral is a 4 sided that may or may not have parallel sides.
Polyhedron* * * * *A polyhedron is a 3 dimensional figure, not its face! The face of a 3-d figure is a plane figure. It may be a polygon, of a circle or some irregular shape. The main requirement is that it is a plane (2-d) figure: if not, it is not usually called a face.
A rhombus (UK), or rhomboid (US), is a quadrilateral parallelogram which can have no right angles. An example is the plane shape we refer to as a 'diamond'. A right-angled rhombus is called a square. If only two sides of the quadrilateral plane figure are parallel, it is called a trapezium (UK), or trapezoid (US). The two sides which are not parallel may or may not be of equal lengths. If their lengths are equal the shape is called an isoscoles trapezium;
