Q8 of 184 Page 11

ABCD is a square having a length of a side 20 units. Taking the centre of the square as the origin and x and y-axes parallel to AB and AD respectively, find the coordinates of A, B, C and D.

Square ABCD. Center = O(0,0) Origin.


AB = BC = 20 units.


Y-coordinates of AB = = -10


Y-coordinates of AD = = 10


∴the coordinates are :-



A(-10,-10)


B(10,-10)


C(10,10)


D(-10,10)
