prove an isosceles trapezium is cyclic

Asked by  | 7th Jun, 2008, 07:25: PM

Expert Answer:

Consider a trap ABCD suc that AB//CD  and AD = BC.

Therefore A  = B..

But A+D=180°(Co- interior angles are supplementary)

So B + D = 180°

Similarly we can show that Anges A and C are supplementay.

 so the given trapezium is cyclic
