Algebra.Com's Answer #25685 by venugopalramana(3286) You can put this solution on YOUR website! PQRS in a parallelogram,Q and S are joined to any point M on the diagonal PR of the parallelogram.Prove that area of the triangle PQM=area of triangle PSM \n" ); document.write( "IN THE DIAGRAM ,DRAW ST FROM S AND QV FROM Q ,PERPENDICULAR TO PR THE DIAGONAL ,MEETING IT AT T AND V RESPECTIVELY. \n" ); document.write( "NOW PARALLELOGRAM PQRS IS DIVIDED IN TO 2 EQUAL PARTS BY DIAGONAL PR(EASILY PROVED BY SSS ..PQ=RS,PR=PR AND PS=QR) \n" ); document.write( "SO AREA OF TRIANGLE PRS=AREA OF TRIANGLE PQR.. \n" ); document.write( "THEY HAVE SAME BASE PR. \n" ); document.write( "HENCE THEIR ALTITUDES TO THAT SAME BASE ARE EQUAL \n" ); document.write( "THAT IS ST=QV \n" ); document.write( "NOW TRIANGLES PQM AND PSM HAVE SAME BASE PM. \n" ); document.write( "THEIR ATITUDES TO THAT BASE ST AND QV ARE EQUAL.HENCE AREA OF TRIANGLE PQM=AREA OF TRIANGLE PSM \n" ); document.write( " |
