- 3Triangle PQR has vertices P(2, 1), Q(2, 4) and R(5, 1). It is first reflected in the y-axis, then translated by the vector .(a)Find the coordinates of the image of P after both transformations.[3 marks](b)Find the coordinates of the image of R after both transformations.[3 marks]

- 4Triangle XYZ has vertices X(1, 1), Y(4, 1) and Z(1, 3). Triangle X'Y'Z' is the image of XYZ under a rotation of 180 degrees about the point (2, 2).(a)Find the coordinates of X', Y' and Z'.[4 marks](b)Triangle X'Y'Z' is then reflected in the line x = 2 to give triangle X''Y''Z''. Find the coordinates of X'', Y'' and Z''.[4 marks](c)Describe fully the single transformation that maps triangle XYZ directly onto triangle X''Y''Z''.[5 marks]
