Dear Student,

Please find below the solution to the asked query :

So, other 2 vertices are B3,1 and D3,6
Now, equation of line joining x1,y1 and x2,y2 isy-y1x-x1 = y2-y1x2-x1So, equation of AB joining A1,2 and B3,1 isy-2x-1 = 1-23-1⇒x+y = 3equation of BC joining B3,1 and C5,5 isy-1x-3 = 42⇒2x-y = 5equation of CD joining C5,5 and D3,6 is    y-6x-3 = -12⇒x+2y= 15equation of DA joining D3,6 and A1,2 is    y-2x-1 = 42⇒2x-y = 2

Hope this would clear your doubt

Do let us know in case of any further concerns
