Prove the sum of quadrilateral is360 |
|
Answer» Draw a diagonal then quad is devided into 2 triangle the sum of all angles of triangle is 1801st triangle +2nd triangle =quadAngles of 1st triangle +angles of 2nd triangle =angle of quad180+180=360 H•p• Given : ABCD is a quadrilateral Const ji on aProof two triangle is form hence sum of all angle of a triangle is 180 hence sum of all angle of two triangle is 180*2=360 We know that there are four angles in a quadrilateral and all of thase are 90°.So,/_ A+/_B+/_ C +/_ D = sum of qudrilateral90°+90°+90°+90°=sum of quadrilateral360° =sum of quadrilateral Hence prove -------------------- Sorry iam not solving your problem Angle-aQuadriletral-qAa |
