Question

In the complex plane referred to a direct orthonormal system (0; ü; ö),consider the points A and B

such that: ZA = 1 and zg = i.

Let h be the homothecy with center A and ratio k = -2.

Let r be the rotation with center B and angle a =5.

1) Write the complex form of h and of r.

2) Consider the transformation S = hor.

a) Determine the nature of

S.

b) Write the complex form of S then deduce the affix of its center 2. 3) Consider the transformation R = Soh-1

a) Prove that R is a rotation whose angle is to be determined. b) Write the complex form of R then deduce the affix of its center 2'.
