Given below are the steps of construction of a quadrilateral WXYZ, where WX = 7.5 cm, XY = 9 cm,
∠W = 80° , ∠X = 115° and ∠Y = 110° .
Which of the following is a wrong step?
(i) Draw WX = 7.5 cm.
(ii) Draw ∠AWX = 80° at W and ∠BXW = 115° at X.
(iii) With X as a centre and radius 9 cm, draw an arc
to intersect XY at Y.
(iv) Draw ∠XYZ = 110° such that ZY meets WA at Z.
A(iii) and (iv) only
