Question

Circle A: center (2, 3) and radius 5. Circle B: center (-1, 4) and radius 10. Which of the
following is the necessary transformation (translation; dilation) from B to A to prove
that the two circles are similar?

    Answer:

    see explanation

    Step-by-step explanation:

    The centre of circle B requires to be coincident with centre of circle A

    (- 1, 4 ) → (2, 3 )

    That is a translation of < 3, – 1 >

    This ensures that the circles are concentric ( have the same centre )

    radius of B is 10 and radius of A is 5, thus

    dilatation = [tex]\frac{5}{10}[/tex] = [tex]\frac{1}{2}[/tex]
