Use ruler and compass for this question.Construct a circle of radius $4.5\,\text{cm}$. Draw a chord. $A B = 6\,\text{cm}$.(i) Find the locus of points equidistant from $A$ and $B$.Mark the point where it meets the circle as $D$.(ii) Join $A D$ and find the locus of points which are equidistant from $A D$ and $A B$. Mark the point where it meets the circle as $C$.(iii) Join $B C$ and $C D$. Measure and write down the length of side $C D$ of the quadrilateral $A B C D$.
