Here we go with an example:

“In the absence of the teacher in the classroom , all students chose to play quietly.
As a result, the student commenced their activities .One of the students suggested a
game , but the rest were hesitant to join .
Another student took a piece of paper and started doodling .
This sparked a new idea among the students, who then silently grabbed their own paper
to doodle, ultimately producing a curve “

Let we start here with an explanation:

A curve is a line that isn’t straight and can twist and turn in any direction .
It flow continuously without any interruption and can from different shape based on how it
bends

TYPES OF CURVE

OPEN CURVE:
A curve that does not enclose a space or come back to its starting point .
Eg; A circle ,an oval or the boundary of a triangle or square.

CLOSED CURVE :
A curve that starts and ends at the same point ,enclosing a space.
Eg; A circle ,an oval or the boundary of a triangle or square.

In the field of geometry , curves can be categorized as either simple or complex .Simple
curves do not intersect themselves while complex curves do. An example of a simple closed
curve is a circle , whereas a figure -eight shape serves as an illustration of a closed curve.
