Does a Circle Have an Edge?
Does a Circle Have an Edge?
Chloe Bennett••5 min read
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.
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.
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."
