 Hello and welcome to the session. In this session we discussed the following question which says are the given figures, simple closed figures give reasons. First of all let's define a simple closed figure, a closed figure which does not intersect itself is called a simple closed figure. This is the key idea for this question. Now we see the solution. These are the three given figures. Now as you can see these are all closed figures that is the figures A, B, C are the closed figures since they begin and end at the same point as you can see. Now let's see if they are simple closed figures. Now as the given three figures do not intersect itself therefore the figures A, B, C are simple closed figures thus the given figures are simple closed figures as they do not intersect itself. With this we complete the session. Hope you have understood the solution of this question.
