In this question we have been given four coordinates of four points.
00:08
So point p, the coordinates 1, 1, or point q coordinates are 2 .4 and point r as coordinates 5 .6 and as as coordinate 4.
00:32
3 we need to prove that quadrilateral formed using given point using given points is a parallel is a parallelogram so to solve this question we take these four points and draw, try to draw on a graph to find eject structure.

So this is one x -axis, two, three, four, five and on y -axis we have one, two, three, four, five.

5 6 so the first point is 1 .1 second point is q 2 .4 so this is there and third point is are 5 .6 5 .6 somewhere here and point s is 4 .3 4 .3 is somewhere here so when we join these all points we get this structure and points are p q r and s and their coordinates are 1 .1 2 .4 r is 5 .6 and s is 4 .3 so now we will find the distance or length of pq so pq is a formula is x2 minus x1 so 2 minus 1 so 2 minus 1 whole square plus y2 minus y1 4 minus 1 whole square so when we solve it we get pqs square root 10 similarly we will find for q r 5 minus 2 whole square plus 6 minus 4 whole square so qr is equal to square root 13.

Then we have rs.
04:25
Rs equal to 5 minus 4 whole square plus 6 minus 3 whole square.
04:39
So rs equal to square root 10...
