GIVEN : In Trapezium ABCD,
AB || CD
AB = 8 cm
BC = 6cm
CD = 4cm
∠B = 60o.
Step1 : draw a rough sketch and mark the measurements given.
As it is given that AB || CD , so ∠B + ∠C = 180° (linear pair). So ∠C = 180° – 60° = 120°
Step 2 : draw ΔABC using SAS construction rule with measures AB = 8 cm, ∠B = 60o and BC = 6 cm.
Step 3 : construct ∠C = 120° and draw CY.
Step 4 : with center ‘C’ and radius 4cm (CD = 4 cm) draw an arc to intersect CY at D. Join A,D . ABCD is the required quadrilateral (trapezium).
