If you consider an edge to be a subset of pointsintersecting with some tangent line, then a circle has aninfinite number of edges (one for each point, since everytangent line intersects at exactly one point). A circlewould have zero edges under this definition. Forpolygons, these two definitions coincide..
Consequently, how many edges are there in a circle?
0
Furthermore, does a sphere has an edge? An edge is the place where two faces meet.Edges are straight; they cannot be curved. Cones,spheres, and cylinders do not have any edgesbecause they do not have any flat sides. The place where twoor more edges meet is called a vertex.
Subsequently, one may also ask, what is the curved edge of a circle called?
A circle is a curved line that runs arounda centre point. Every bit of the curved line is the samedistance from the centre. The line of this fold is an importantpart of the circle, called the diameter. One half ofthis line (from the centre to the edge of the circle)is known as the radius.
Is circle a polygon?
A circle is not a polygon as it does nothave straight sides.

Does a circle have an angle?
The angles of a triangle always add up to 180degrees. The closest thing a circle has to a side is thecircumference (the circle itself). The“angle” of a circle is 360 degrees– all the way around.Does a circle have 0 or infinite sides?
If you think of it as the limit of an n-sidedregular polygon, then one can justify the answer that the circlehas infinitely many infinitesimal sides. Perhaps theappropriate response is "there is no natural way of saying what theside of a circle is."How many edges does a triangle?
three
How many sides has a semi circle?
two sides
Is a circle made of straight lines?
A circle is a plane figure contained by oneline, which is called circumference, and is such, that allstraight lines drawn from a certain point within the figureto the circumference, are equal to one another.Does a circle have a face?
The flat surfaces of a solid figure are itsfaces, or sides as they are commonly called. Because acircle is a flat, plane shape, it is a face. Butbecause it is round around the outside, it does not form anyedges or vertices. A cylinder has two circular faces butalso no edges or vertices.How many sides does a sphere have?
two sides
What is a radius of a circle?
The radius of a circle is the distance from thecenter of the circle to any point on its circumference. Theeasiest way to find the radius is by dividing the diameterin half.Is curve a line?
In mathematics, a curve (also called a curvedline in older texts) is, generally speaking, an objectsimilar to a line but that need not be straight. Thus, acurve is a generalization of a line, in that it maybe curved.What are the types of circle?
The following video gives the definitions of acircle, a radius, a chord, a diameter, secant, secant line,tangent, congruent circles, concentric circles, andintersecting circles.Is Triangle a curve?
A triangle is a simple closed curve orpolygon which is created by three line-segments. In Euclideangeometry, any three points, specifically non-collinear, form aunique triangle and separately, a unique plane (known astwo-dimensional Euclidean space).Does a circle have an end?
in case of a ray there is one endpoint .only the sourceof the ray with no significant end point . a circleis basically a curve constituted by infinite number of pointsmaintaining always a same distance from the center point .calledcenter of circle .Do 2d shapes have vertices or corners?
Vertices of Two-DimensionalShapes Each point where two straight edges intersect is avertex. A triangle has three edges -- its threesides. It also has three vertices, which are eachcorner where two edges meet. You can also see from this definitionthat some two-dimensional shapes do not have anyvertices.Does Euler's formula work for all shapes?
Euler's formula deals with shapes calledPolyhedra. A Polyhedron is a closed solid shape which hasflat faces and straight edges. An example of a polyhedron would bea cube, whereas a cylinder is not a polyhedron as it has curvededges. Euler's Formula does however only work forPolyhedra that follow certain rules.Is a cone a polyhedron?
The faces of the polygon are known as "polygons" becausethey contain straight sides. It is known that the polyhedronis bounded by the "straight lines" and due to the "curved surfaces"of a cone. The solid which contains a base like circle andcurved surface with single vertex is calledcone.What is vertices and edges?
Vertices is the plural form of the wordvertex. A vertex is a single point. It joinsedges together in a shape. Often, we also might call it acorner or just a point. An edge is a linesegment.
