Answer»

calculate the area of triangle agar zero aagaya to points collinear hai

1) slope AB = (-0.5-2)/(1-0) = -2.5/1 slope BC = (-3+0.5)/(3-1) = -2.5/1 since they are equal , so collinear

2) slope PQ = (8/5-2)/(2-1) = -2/5 slope QR = (6/5-8/5)/(3-1) = -2/5 since they are equal , so collinear..

area (∆ABC)=1/2{0(-0.5+3)+1(-3-2)+2(2+0.5)} =1/2{0-5+5} =1/2×0 =0So this point is collinear
