Draw a right triangle ABC of hypotenuse BC s.t AB = 5cm and AC = 9cm.

  1.  Use Thales to plot a point M on [AC] s.t 

    \frac{{AM}}{{AC}}=\frac{3}{5}

    .
  2. Construct triangle AB'C' , the reduction of triangle ABC by scale factor

    \frac{1}{3}

  3. Calculate BC and deduce the length of B'C'.
