Plane shapes can be defined as two-dimensional geometric figures that exist on a flat surface, known as a plane. These shapes have only length and width, with no depth or thickness. They are characterized by their boundaries, which can be made up of straight sides or curved lines.

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. Fi...
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 \(R\) lies on its boundary. Together the interior of the cur...

(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...

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...
In plane geometry, the two-dimensional shapes are flat shapes and closed figures such as circles, squares, rectangles, rhombus, etc. In solid geometry, the three-dimensional shapes are cube, cuboid, cone, sphere and cylinder. We can observe all these shapes in our daily existence also.
Images. Area Between Curves. Two-dimensional geometry is the study of flat shapes like curves, lines, polygons, etc. that can be drawn on a piece of paper. On the other hand, three-dimensional geometry is the study of three-dimensional objects such as cubes, cylinders, spheres, and so on.
A geometric figure is any combination of points, lines, or planes. Geometric figures are often classified as space figure, plane figure, lines, line segments, rays, and points depending on the dimensions of the figure.
Closed. The line segments or curves forming a closed figure are continuous, meaning there is no break. The lines/curves must also form a closed region to be considered a closed shape. A closed figure has area and perimeter. The following are a few examples.

Dec 21, 2020 · In this chapter we’ll explore new ways of drawing curves in the plane. We’ll still work within the framework of functions, as an input will still only correspond to one output. However, our new techniques of drawing curves will render the vertical line test pointless, and allow us to create important – and beautiful – new curves.
