Simple closed curve made of line segments
Webb29 mars 2024 · The images or shapes that are closed by the line or line-segment are called simple closed curves. A Closed curve’s starting point and ending points are the same and a closed curve doesn’t cross its path. Triangle, quadrilateral, circle, pentagon, …etc. are an example of the simple closed curves. Simple closed curves are Webb$\begingroup$ @Pete L. Clark This answer is helpful, because a closed curve in an open set in $\mathbb{R^n}$ is homotopic to a piecewise-linear curve made of finitely many line segments (This is not hard to prove, with the aid of the paving lemma).

WebbIn our day-to-day lives, we come across various plane surfaces, such as the top of our study table, blackboard, etc. In Chapter 15 of Class 8, we shall discuss concepts based on polygons (A polygon is a closed curve formed by the line segment where (i) no two line segments intersect except at their end-points and (ii) no two line segments with a … WebbA simple closed curve made of only line segments is called a polygon. A polygon is a simple closed curve made up entirely of line segments. A polygon has at least 3 sides. …
WebbSo, for example, you can have a geometric figure that is not connected (like the lower case letters "i" and "j"), or you can have a geometric figure that is composed of a simple closed curve with a line segment sticking out of it (like the letter "P"). WebbIdentify the shape. A curve made entirely of line segments is called a polygon. A concave polygon is a polygon that has at least one exterior angle less than 180 °. A convex polygon is a polygon that exterior angles are greater than 180 °. Since ∠ C and ∠ F are less than 180 °, the figure is concave.
A closed curve is thus the image of a continuous mapping of a circle . If the domain of a topological curve is a closed and bounded interval , the curve is called a path, also known as topological arc (or just arc ). A curve is simple if it is the image of an interval or a circle by an injective continuous function. Visa mer In mathematics, a curve (also called a curved line in older texts) is an object similar to a line, but that does not have to be straight. Intuitively, a curve may be thought of as the trace left by a … Visa mer Interest in curves began long before they were the subject of mathematical study. This can be seen in numerous examples of their decorative use in art and on everyday objects dating back to prehistoric times.
