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.
Fig (i), (ii), (v), (vi) and (vii) are simple closed curves.
Fig (i) and (ii are polygons. Polygons are minimum three sided enclosed figure.
Fig (ii) is a convex polygon. In a convex polygon all the vertices are pointing outwards.
Fig (i) is a concave polygon. In a concave polygon all the vertices are not pointing outwards.
Fig (viii) is not a curve.
