Solution

2. Let ABCD be a square of side 2a. Find the coordinates of the vertices of this square when
(i) A coincides with the origin and AB and AB and coordinate axes are parallel to the sides AB and AD respectively.
(ii) The center of the square is at the origin and coordinate axes are parallel to the sides AB and AD respectively.

Solution

(i) Coordinate of the vertices of the square of side 2a are :
A(0, 0), B(2a, 0), C(2a, 2a) and D(0, 2a)
(ii) Coordinate of the vertices of the square of side 2a are :
A(a, a), B(-a, a), C(-a, -a) and (a, -a)
