prove an isosceles trapezium is cyclic
Asked by | 7th Jun, 2008, 07:25: PM
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
