Question

Classify each of them on the basis of the following : Simple Curve Simple Closed Curve Polygon Convex Polygon Concave Polygon Who so ever answers this I will mark him or her as Brainliest.

Answer 1

★ Simple Curve :-

A curve which does not cross itself is a simple curve.

So,according to the above picture we can say that :- 1),2),5),6) and 7) are simple curve.

★ Simple closed curve :-

A curve which does not cross itself and is closed is a simple closed curve.

So,according to the above picture we can say that :- 1),2),5),6) and 7) are simple closed curve.

★ Polygon :-

A simple closed curve is made up of only line segment is called a polygon.

So,according to the above picture we can say that :- 1) and 2) are polygon.

★ Convex Polygon :-

In a convex polygon,no part of their diagonal is in the exterior.

So,according to the above picture we can say that :- 2) are convex polygon.

★ Concave Polygon :-

In a concave polygon,diagonal can be in exterior.

So,according to the above picture we can say that :- 1) is a concave polygon.
