Mathematics
Construct a quadrilateral ABCD; if :
AB = 6 cm, CD = 4.5 cm, BC = AD = 5 cm and ∠BCD = 60°.
Answer
Steps:
Draw BC = 5 cm.
With C as centre, draw an arc of any suitable radius which cuts BC at point R.
With R as centre and the same radius as taken in step 2, draw one more arc which cuts the previous arc.
Join I with C and produce upto any point P.
∠PCB = 60°.From PC cut CD = 4.5 cm.
With D as center and radius equal to 5 cm, draw an arc.
With B as center and radius equal to 6 cm, draw an arc which intersects the arc drawn in step 4 at D.
Join BA and AD.
Hence, ABCD is the required quadrilateral.
