Q3 of 805 Page 18

Construct a quadrilateral ABCD in which AB = 7.7 cm, BC = 6.8 cm, CD = 5.1 cm, AS = 3.6 cm and ∠C = 120°.

Step 1: Draw the side CD = 5.1 cm



Step 2: Draw = 120°



Step 3: Taking C as centre, draw an arc of radius 6.8 cm on CX cutting CX at point B



Step 4: With B as centre and radius equal to 7.7 cm draw an arc



Step 5: With D as centre and radius equal to 3.6 cm draw another arc to cut down arc of step 4 at a point A



Step 6: Join DC and BC



ABCD is the required quadrilateral
