## What is a curved line in math?

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..

## What is a curved shape?

1. curved shape – the trace of a point whose direction of motion changes. curve. bell-shaped curve, Gaussian curve, Gaussian shape, normal curve – a symmetrical curve representing the normal distribution.

## What do you call a triangle with a curved side?

Reuleaux triangles have also been called spherical triangles, but that term more properly refers to triangles on the curved surface of a sphere. … Because of this property of rotating within a square, the Reuleaux triangle is also sometimes known as the Reuleaux rotor.

## What are the examples of curved lines?

There are many examples of curved lines like the alphabets – C and S. Whereas the letters A, M, N, L, etc are not the examples of curves since they can be formed by joining the line segments (or straight lines).

## Is a circle straight or curved?

Circles. Probably the most common two-dimensional curved shape is a circle. In order to work with circles (and other curved shapes) in geometry it is important to understand the key properties of a circle: A line straight across the centre of a circle is the diameter.

## How do you explain a curve?

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. 2. Downward curve: A curve that turns in the downward direction is called a downward curve.

## Is there a curved line?

If a point moves in only one direction, we get a straight line. A line that is not straight is a curved line. If a point does not move in one direction, we get a curve.

## How do you find a curved area?

The formula looks like this: surface area = 2(pi x radius squared) + 2(pi x radius x height). Using the same example as before, the equation would be: 2(3.14 x 9 x 9) + 2(3.14 x 9 x 20) = 2(254.34) + 2(565.2) = 508.68 + 1,130.4 = 1,639.08 squared inches.

## What is the curved edge of a circle called?

arcSector is the space between two radii (plural of radius) and an arc (the curved edge of the circle).
