# Question: Can A Line Not Be Straight?

## What is a curved line called?

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..

## Does a line need to be straight?

If a line is not straight, we usually refer to it as a curve or arc. In plane geometry the word ‘line’ is usually taken to mean a straight line. If a set of points are lined up in such a way that a line can be drawn through all of them, the points are said to be collinear.

## What do you call a not straight line?

Something crooked is not straight, like a trail through the woods, or your cousin’s unfortunate set of teeth.

## Is it impossible to draw a straight line?

You can draw a physical line between two points, so a good model for that should allow a mathematical line between two points. … A real line will have thickness, it won’t be perfectly straight, and it can have gaps. A mathematical line won’t have thickness, it will be perfectly straight, and it won’t have gaps.

## What are the 7 types of lines?

There are many types of lines: thick, thin, horizontal, vertical, zigzag, diagonal, curly, curved, spiral, etc. and are often very expressive.

## Why is it so hard to draw a straight line?

Because of the way our bodies and brains work. Our joints are rotational. … That’s right, when drawing a straight line, your body is turning linear motion into rotational motion into linear motion. Our tendons are fixed near the pivots, so we have to pull very hard against our bones.

## What does a diagonal line look like?

Diagonal is a kind of straight line. A diagonal line does not go straight up, down, or across. For example, in geometry a diagonal is any line that goes between the corners of a polygon. So a square has two diagonals, and a five-sided shape has five diagonals.

## Can a straight line be curved?

What About Curves? A curve is not a straight line, just as a straight line is not a curve. A curved line contains points that are not linear to two given points. The curve moves in other directions from the straight line created by joining collinear points.

## Can a line have 3 points?

These three points all lie on the same line. This line could be called ‘Line AB’, ‘Line BA’, ‘Line AC’, ‘Line CA’, ‘Line BC’, or ‘LineCB’ .

## 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.
