A curved shape does not have any straight lines. In a circle the line curves continually, meaning that the circle is a curved shape.
distortion of a size, shape, distance, or area occurs.
Polygon: A closed shape bounded by straight lines.
limited shape possible to be cut; can only cut straight lines and tight curves; long cutting, preparation and maintenance time
If the shape has three straight lines and no other lines then it has to be a triangle
A shape with 4 straight lines in which there are 2 parallel and 2 unparallel lines is called a Trapezium.
It is the total length of its boundary. There is no need for the boundary to be made up of straight lines or even smooth curves. However, fractals do cause problems.
A shape made up of line segments is a shape with straight lines, or a polygon. for example, a square has straight lines, or is made up of line segments. A circle is not in that category because it has no straight lines, they are curved.
Not really, but if you have many lines it can look like a curved shape.
