Question

( -A B, A D quad ) are coordinate anis
thence ( c=(a, a) )

# at the 1213 2) 13 3) - V3 4) 0 6. The side of a square ABCD is ‘a’units. A,B,C,D are in the anti-clockwise order. If AB and AD are coordinate axes. Then the coordinates of C are 2) (-a, a) 1) (a -a) 4) (aa) 3) (-a,a). 33. If the points (a+b, a-b), (2a+b, 2a-b), (a-b, a+b) are the consecutives vertices of a parallelogram then, its fourth vertex is 3) (-6,b) 4) (6,2b) 2) (2b,b) 1) (6, 6) men OP- DA= OP to Torget HIS of the median AD
