Using a ruler and a compass construct a triangle $ABC$ in which $AB = 7\,\text{cm}$, $\angle CAB = 60^{\circ}$ and $AC = 5\,\text{cm}$. Construct the locus of:(i) points equidistance from $AB$ and $AC$.(ii) points equidistant from $BA$ and $BC$.Hence construct a circle touching the three sides of the triangle internally.
