First of all we draw a rough sketch of given measurements :
Steps of Construction
(i) First of all we draw a line segment MO = 6 cm.
(ii) At point M and O construct ∠MOY 105° and ∠OMX = 60° with MO respectively.
(iii) Cut an arc of 4.5 cm from point O on ray OY and mark the point as R.
(iv) At point M construct ∠OME = 60° with OM. Intersecting MX at E.
(v) Thus we. obtained required quadrilateral MORE.
