Construct quadrilateral with the measurements given below:

Quadrilateral ABCD with AB = 4.5 cm, BC = 5.5 cm, CD = 4 cm, AD = 6 cm and AC = 7 cm

GIVEN : In quadrilateral ABCD ,

AB = 4.5 cm


BC = 5.5 cm


CD = 4 cm


AD = 6 cm


AC = 7 cm


PROCEDURE :


Step 1 : draw a rough sketch of the quadrilateral ABCD with the given measurements.



Step 2 : Construct ΔABC using SSS construction property with AB = 4.5 cm , BC = 5.5 cm and AC = 7 cm.



Step 3 : we have to locate the 4th vertex ‘D’ . it would be on the other side of AC. So , with center A and radius 6 cm(AD = 6 cm) draw an arc and with center C and radius 4 cm (CD = 4 cm) draw another arc to cut the previous arc at D.



Step 4 : join A,D and C,D to complete the quadrilateral ABCD.
