# What is a curve in geometry?

In analytic geometry, a curve is continuous map from a one-dimensional space to an -dimensional space. Loosely speaking, the word "curve" is often used to mean the function graph of a two- or three-dimensional curve.

## What is a curve in math geometry?

curve, In mathematics, an abstract term used to describe the path of a continuously moving point (see continuity). Such a path is usually generated by an equation. The word can also apply to a straight line or to a series of line segments linked end to end.

## What is a curve simple definition?

A curve is a continuous and smooth flowing line without any sharp turns. One way to recognize a curve is that it bends and changes its direction at least once.

## What are the types of curve?

Answer: The different types of curves are Simple curve, Closed curve, Simple closed curve, Algebraic and Transcendental Curve.

## WHAT IS curve in a graph?

A graph curve is a connected union of projective lines, each line meeting three others in ordinary double points.

## Is straight line a curve?

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.

## Is circle a curve?

Specifically, a circle is a simple closed curve that divides the plane into two regions: an interior and an exterior.

## Is Square a curve?

Yes! A square is a closed curve.

## How do you find the curve?

If κ=a/c and τ=b/c, where c=√a2+b2, then your curve is congruent to (differs by a rigid motion from) the circular helix α(t)=(acost,asint,bt). Given κ and τ, you can determine a and b by algebra.

## What is the purpose of curve?

Curves are regular bends provided in the lines of communication like roads, railways etc. and also in canals to bring about the gradual change of direction. They are also used in the vertical plane at all changes of grade to avoid the abrupt change of grade at the apex.

## What is a curved graph called?

Parabolas. A parabola is a curved graph produced by a quadratic function, one which contains a "squared" x-term.

## What is a slope of a curve?

The slope of a curve at a point is equal to the slope of the straight line that is tangent to the curve at that point.

## What is a open curve in mathematics?

An open curve is a curve where the beginning and end points are different.

## What is a curve Class 8?

Curves. A curve is a line or outline which gradually deviates from being straight for some or all of its length. A simple curve does not cross itself at any point. Aclosed curve is a curve with no endpoints and which completely encloses an area.

## Is a triangle curved?

A triangle is a polygon with three edges and three vertices. A polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain (or polygonal circuit). From those two definitions, it should be clear that no, a "curved triangle" is not a triangle.

## Why circle is a curve?

A circle is a curved line that runs around a center point. Every part of the curved line is the same distance from the center. A circle can be folded into two halves that are exactly the same, which means that it is symmetrical. The line of this fold is an important part of the circle, called the diameter.

## How many curves are in a circle?

In our primary education resources, we say that a circle has one curved side.

## Can a line have a curve?

A curved line is defined as a line that is not straight but is bent. Ideally, a straight line holds a zero curvature, whereas a curved line has a non-zero curvature and is continuous and smooth. Curves are prominent figures found everywhere around us.

## Is circle a closed curve?

Triangle, quadrilateral, circle, etc., are examples of closed curves. A curve which starts and ends at the same point without crossing itself is called a simple closed curve. A circle is a simple closed curve.

## Which is a closed curve?

In the plane, a closed curve is a curve with no endpoints and which completely encloses an area.

## What is open curve and closed curve?

Open curve- An open curve is a curve in which there is no path from any of its point to the same point. Closed curve- This is a curve that forms a path any of its point to the same point.

## What is the equation for a curved line?

These equations take the form of f(x) = ax^2 + bx + c, and can be solved a variety of ways; students will often be asked to find the solutions, or the zeros, of these graphs, which are the points at which the graph crosses the x-axis.
