Question

In Trapezium ABCD, x is a point on AB so that DX//BC ...Show that AXD is a isosceles triangle​

Answer 1

given , ABCD is trapezium in which DX//BC

prove,AXD is isosceles ∆

proof, take AD and BC are // Side of trapezium so , AD// BC

DX//BC , SO AD//DX//BC

therefore AD // DX

so AD = DX

in isosceles triangle two sides are equal

therefore adx is isosceles triangle proved
