Answer and Explanation:
A circle does not have any sides as it's made up of arcs, creating a continuous line that meets at two ends. All parts of a circle are of equal distance to the center of a circle.An edge is the place where two faces meet. Edges are straight; they cannot be curved. Cones, spheres, and cylinders do not have any edges because they do not have any flat sides. The place where two or more edges meet is called a vertex.
In convexity theory, there is a notion called an extreme point that generalizes the notion of vertex (or corner) of a polygon. For this definition every point on a circle is an extreme point so it makes sense to say it has infinitely (uncountably!) many corners. Though the notion of side is not as good.
radius. Sector. Sector is the space between two radii (plural of radius) and an arc (the curved edge of the circle). It is a slice of a circle, rather like a slice of a pie.
For a regular polygon with 10,000 sides (a myriagon) the internal angle is 179.964°. As the number of sides increase, the internal angle can come very close to 180°, and the shape of the polygon approaches that of a circle. However the polygon can never become a circle.
How Many Angles Can a Circle Have? A circle only has one angle. It is named a full angle and measures 360 degrees or 2 pi radians. If two radius lines combine and become one line, the angle is 360 degrees.
For example, circles and ovals are made from a single edge with no corners. Since there are no separate edges intersecting, these shapes have no vertices. A semi-circle also has no vertices, because the intersections on the semi-circle are between a curved line and a straight line, instead of two straight lines.

A cylinder has 3 faces - 2 circle ones and a rectangle (if you take the top and bottom off a tin can then cut the cylinder part on the seam and flatten it out you would get a rectangle). It has 2 edges and no vertices (no corners).
If you think of it as the limit of an n-sided regular polygon, then one can justify the answer that the circle has infinitely many infinitesimal sides.
No. A circle has no straight line segment. Yet, if you take the limit as the number of sides increases to infinity, then the polygon approaches the circle, and the limit of these polygons is the circle. Every one of those polygons is composed of straight line segments, but their limit, the circle, has no line segments.
For this definition every point on a circle is an extreme point so it makes sense to say it has infinitely (uncountably!) many corners. Though the notion of side is not as good. If the definition is line segment joining two vertices then the answer would be 0 for the circle.

The circle is a two-dimensional (2D) shape. It only has two measurements, such as length and height, and is usually called a 'flat' shape.
2D shapes: sides and vertices
When we talk about 2D shapes, we talk about sides and angles. The angles of a 2D shape are also sometimes referred to as 'vertices' (singular: vertex).A circle does not have sides. A "side" usually refers to the sides of a polygon, such as a square or a triangle. Although a circle is a shape, it is not a polygon, so it does not have sides. It can't have infinitely many sides because infinity is not a number, and you can't actually have infinity of something.
Because the fixed point (center) and the equidistant moving point that generates the locus (circumference) lie in the same plane, the points of a shape in a plane can be reached by its (x, y) coordinates. Hence it is 2D shape. What shape results from drawing a circle (fixed radius) on a torus?
Answer and Explanation:
A circle does not have any sides as it's made up of arcs, creating a continuous line that meets at two ends. All parts of a circle are of equal distance to the center of a circle.A straight line from the center of a circle to the edge is called the radius. A straight line that passes from one side of a circle to the other through the center is called the diameter. The distance around the outside of a circle is called the circumference.
In geometry, a two-dimensional shape can be defined as a flat plane figure or a shape that has two dimensions – length and width. Two-dimensional or 2-D shapes do not have any thickness and can be measured in only two faces.
- In geometry, the rhombicosidodecahedron, is an Archimedean solid, one of thirteen convex isogonal nonprismatic solids constructed of two or more types of regular polygon faces.
- It has 20 regular triangular faces, 30 square faces, 12 regular pentagonal faces, 60 vertices, and 120 edges.
Answer and Explanation:
A circle does not have any sides as it's made up of arcs, creating a continuous line that meets at two ends. All parts of a circle are of equal distance to the center of a circle.a circle is basically a curve constituted by infinite number of points maintaining always a same distance from the center point . called center of circle . so circle has no endpoint . in another words circle has ZERO endpoint.
From Wikipedia, the free encyclopedia. Convex circular triangle. Circular horn triangle. In geometry, a circular triangle is a triangle with circular arc edges.
The flat surfaces of a solid figure are its faces, or sides as they are commonly called. Because a circle is a flat, plane shape, it is a face. But because it is round around the outside, it does not form any edges or vertices. A cylinder has two circular faces but also no edges or vertices.
Next doubt arose, as the sides of the regular polygon tends to a larger number (infinity), the regular polygon is actually getting transformed into a circle. While approaching this, the circle is considered to be an infinite sided regular polygon.
The three most important properties to remember are the circumference, which is the distance around the shape; the diameter, which is the distance from one end of the circle to the other crossing through the center; and the radius, which is half of the diameter.
