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?

curve line ant

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 Line Curved 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.

The above letters and numbers are made by joining straight lines.

Curved lines form open and closed curves.

Open curves: The examples of open curves are

open curves

Closed Curves: The examples of closed curves are.

close curves

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.



  Fun Fact

  • Geometry, a branch of mathematics, deals with different figures and solids made up of straight and curved lines.
