is it possible to have a quadrilateral with three of its angles equal and the fourth angle thrice of one of the angles? why or why not? answer fast Share with your friends Share 2 Vijay Kumar Gupta answered this Dear student, It is never possible to have a quadrilateral with three ot its angles equal andthe fourth angle thrice ot the angles.Suppose if possible, it is true.Let each of three equal angles of the quadrilateral=xThen the fourth angle will be=3·x=3xSince sum of ll the angles pf a quadrilateral is 360° Therefore, we have: x+x+x+3x=360°⇒ 6x=360°⇒ x=60°Therefore the fourth angle will be 3×60°=180° which is a straight line and cannot be the angle of quadrilateral Regards 2 View Full Answer
