Steps of Construction:
(i) Draw a line segment XY = 4.5 cm
(ii) With the help of a compass, draw an arc of 4.5 cm from Y as centre.
(iii) Again with the help of compass, draw another arc of 5.4 cm from X as centre which intersects the previous arc made by Y.
(iv) Now, mark the intersection as point Z and join it to both X and Y. The required triangle XYZ is obtained.
(v) Draw the bisectors of XY and YZ which meet at point O.
(vi) Now, draw the circle using a compass taking O as centre and radius OX or OY or OZ.
(vii) This circle will pass through the vertices X, Y and Z.
