What is a curved line?
A curve is a continuous line that flows smoothly and without abrupt turns. A curve can be identified easily by observing if it bends and modifies its course at least once. The examples of geometric shapes in which curves can be observed are circles, semi-circles, spheres, and so on.

In mathematics, a curve is an abstract term used to describe the path of an uninterruptedly moving point (see continuity). Such a path is usually given by an equation. A closed curve is a path that repeats itself and thus encloses one or more than one region. Simple examples include circles, polygons, and ellipses.
A curve can be defined as the constant movement of points in all directions. It means that each and every possible shape can be classified as curves because all the shapes are formed by the movement of the points in one or multi-dimension. A curve can be an open curve or a closed curve. The figures below show an example of each type of simple curve...
Curves are categorised into different categories. Let us discuss the different types of curves with examples. The different types of curves are discussed below with figure for better understanding- 1. Simple Curve:A curve that changes its direction but it does not connect itself. A simple curve changes direction but does not criss-cross itself whil...
Let us identify the different types of curves in the given figure based on their properties.We can see that in Figure 1 the curve is a simple closed curve, as an area is bounded by the boundaries of the curve. In Figure 2, the curve is a closed curve, as we observe the smooth surface and continuous edges. Figure 3 is an upward curve. Figure 4 is a ...
A curved line is a line that is bent and not straight. If the curvature is not equal to zero, then it is taken as a curve line. Generally, it is smooth and continuous.
1. The point that is lying inside the closed curve is called its interior 2. The point that is lying outside the closed curve is called its exterior 3. The point that lie on the curve constitute its boundary In the given figure, point P lies in its interior, Q in its exterior, and Rlies on its boundary. Together the interior of the curve with its b...
Q.1. Demonstrate each one of the following with a diagram roughly if possible. (a) A closed curve that is not a polygon. (b) An open curve made up of only line segments. (c) A curve that is neither closed nor simple. Explain. (d) A polygon with two sides. Ans: (a) A closed figure that is not a polygon is shown below: (b) An open curve made up entir...
In this article, we learnt that a curve is a shape or a line that is smoothly drawn in a plane having a bent or turns in it. There are different types of curves such as simple curves, non-simple curves, open curves, closed curves, upward and downward curves, etc. Also, we discussed points that are interior and exterior to a closed figure. We also p...
Q.1. What is called a curve? Ans:A curve is a shape or a line that is smoothly drawn in a plane having a bent or turns in it. Q.2. What is a curve definition suitable for Class 6? Ans:A curve is a path drawn on a sheet of paper without lifting the pencil and without retracing any point of the path except for single points. Q.3. Illustrate some exam...
Curved Line: Definition. A curved line is a type of line that is not straight and is bent. It is continuous and smooth, without any sharp turns. We know that the curvature of the straight line is zero. Hence, when the curvature of a line is not zero, then we call it a curved line.
Jun 27, 2023 · Examples of curves are bicycle wheels, soda cans, and cups in the real world. In the mathematical world, examples of curves include circles, parabolas, and hyperbolas.
Jul 21, 2022 · Two points on a plane determine a line. A line is a one-dimensional figure that is made up of an infinite number of individual points placed side by side. In geometry, all lines are assumed to be straight; if they bend they are called a curve. A line continues infinitely in two directions.
Geometry is a branch of mathematics that deals with shapes, sizes, angles, and dimensions of objects. Explore 2D and 3D shapes, angles in geometry with examples!
An easy way to test for both is to connect two points on the curve with a straight line. If the line is above the curve, the graph is convex. If the line is below the curve, the graph is concave.
