Following are some figures: Classify each of these figures on the basis of the following:


(i) Simple curve (ii) Simple closed curve


(iii) Polygon (iv) Convex polygon


(v) Concave polygon (vi) Not a curve

(i) Simple curve


Fig (i), (ii), (v), (vi) and (vii) are simple curves.


(ii) Simple closed curve


Fig (i), (ii), (v), (vi) and (vii) are simple closed curves.


(iii) Polygon


Fig (i) and (ii are polygons. Polygons are minimum three sided enclosed figure.


(iv) Convex polygon


Fig (ii) is a convex polygon. In a convex polygon all the vertices are pointing outwards.


(v) Concave polygon


Fig (i) is a concave polygon. In a concave polygon all the vertices are not pointing outwards.


(vi) Not a curve


Fig (viii) is not a curve.
