Construct a quadrilateral ABCD in which AB=BD=3.5cm, AD=CD=5.2 and ∠ABC=120o

The given quadrilateral ABCD can be drawn as follows:


Step 1: Draw a line segment AB = 3.5 cm.


Step 2: At B, draw ABX = 120°.


Step 3: Cut BD = 3.5 cm on ray BX


Step 4: At D, draw BDY = 60°. (B + D = 180°)


Step 5: Cut CD = 5.2 cm on ray DY


Step 6: Now, join C to A.


Step 7: ABCD is the required quadrilateral.
