If you take many points and place them one after another, you’ll get a line. If it has no curve in it, has no beginning or end, and continues indefinitely in both directions, then this is a straight line. If the line bends due to a specific location of the points, then it’s a curve. The ends of the curved line may not connect, forming an open curve. When they are connected, you’ll get a closed curve.

Draw a closed curved line so that all its points are in the same plane and at an equal distance from a given point, which is located in the same plane, and you’ll get a separate geometric shape called a circle. If you take the plane inside this circle, you’ll get another geometric shape called a disc.

You need a compass to draw a circle. It’s a special instrument that allows you to inscribe circles and arcs.
