11. A playground is in the shape of a quadrilateral ABCD. It is given that AB = 90 m,
AD = 70 m, LBAD = 115°, LABC= 80° and ZADC = 85⁰.
(a) Using a scale of 1 cm to represent 10 m,
(i) make an accurate scale drawing of the playground.
(ii) Can ABCD be a cyclic quadrilateral? Give reason for your answer.
b) On your diagram, construct
(i) the locus which represents points 50 m from B.
(ii) the locus which represents points equidistant from C and D.
