Curved Line – Definition with Examples

Curved Line

Imagine an ant has to move from point A to point B. What are the different ways in which the ant can reach from point A to point B?

The ant can take several paths to reach from point A to B. The given figures show some of the paths that the ant can take to reach from point A to point B.

curved lines

We see that in the first four figures, the ant changed its direction while traveling from point A to point B, that is, it did not follow one constant direction. However, in the last figure, the ant moved straight, and the distance it moved was the shortest. The movement from one point to another gives rise to straight or curved lines.

Straight LineCurved Line



The shortest line joining any 2 points is a straight line.If a point moves in only one direction, we get a straight line.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.curve line

Circle: A circle is a closed curve formed when a point moves in a plane such that it is at a constant distance from its center.
