Simple curve : A curve that changes its direction, but it does not intersect itself. This type of curve is known as a simple curve
Simple closed curve : A curve has no endpoints, and when it encloses the region or area will form, it is known as the closed curve.
Convex polygon : Polygons that are convex have no portions of their diagonals in their exteriors.
Concave polygon : Polygons that are concave have portions of their diagonals in their exteriors.
