त्रिभुज ABC मा AB = 4.5 से.मी., BC = 5.5 से.मी. र \(\angle ABC = 75^\circ\) दिइएका छन् ।
In triangle ABC, AB = 4.5 cm, BC = 5.5 cm and \(\angle ABC = 75^\circ\) are given.
(a) माथिको नापका आधारमा \(\triangle ABC\) को रचना गर्नुहोस् र \(\triangle ABC\) को क्षेत्रफलसँग बराबर हुनेगरी \(\angle EFC = 60^\circ\) भएको समानान्तर चतुर्भुज FCDE को रचना पनि गर्नुहोस् ।
Construct a \(\triangle ABC\) on the basis of the above measurements and construct a parallelogram FCDE equal in area to \(\triangle ABC\) with \(\angle EFC = 60^\circ\).
(b) कुन अवस्थामा उही समानान्तर रेखाहरूबिच रहेका त्रिभुज र समानान्तर चतुर्भुजको क्षेत्रफल बराबर हुन्छ ? लेख्नुहोस् ।
In which condition, the areas of a triangle and a parallelogram between same parallel lines are equal? Write it.
