Answer

Steps of construction :

  1. Draw a line segment AB = 5 cm.

  2. Draw AX ⊥ AB.

  3. With B as center and radius equal to 5.5 cm draw an arc cutting AX at D. Join BD.

  4. With D and B as center and radii equal to 6 cm and 2.5 cm respectively draw arcs cutting each other at C.

  5. Join DC and BC.

Using ruler and compasses only, construct the quadrilateral ABCD, having given AB = 5 cm, BC = 2.5 cm, CD = 6 cm, ∠BAD = 90° and diagonal BD = 5.5 cm. Construction of Polygons, Concise Mathematics Solutions ICSE Class 9.

Hence, ABCD is the required quadrilateral.
