6. Under a rotation R, triangle OPQ with vertices O(0,0) P(1,0) and Q(0, 1) is mapped onto triangle OP, Q, where P, is the point (0, -1) and Q, is the
point (1, 0)
(a) Draw and label triangle OPQ and triangle o p¹q¹
(b) Describe fully the rotation R.
(c) Find the matrix representation of R-
(d) Find the coordinates of X if the coordinates of its image under R
are (0, -4)​
