In this problem, we have to prove for any correlator, a, b, c, d in a plane, the correlator obtained by joining the midpoints of the adjacent side of a, b, c, d is always a parallelogram.
00:17
So here we can join the midpoints like this, say here, first point is here, then second is the midpoint, here this is the midpoint, and here this is again the midpoint.
00:28
So we can name it as, say, pqrs.
00:31
So here this would be pqrs.
00:35
And now when we are joining the midpoints of the adjacent sides, let's suppose here we are joining p with q and then q is joined with r and then r is joined with s and then s is joined with again p.
00:53
Then we have to prove that pqrs.
00:56
So here we can say we have to prove that to prove that to prove pqrs is a parallelogram.
01:08
Parallelogram that means opposite sides are parallel and equal.
01:13
So, first step is here.
01:18
First step is to join a with c.
01:21
So here we are joining a with c.
01:23
So here we have joined a with c.
01:27
So this is joined with c...
