Expert Answer:

An isoscales trapezium is a cyclic quadrilateral.
But a cyclic quadrilateral can not be always an isosceles trapezium.
 
A cyclic quadrlateral can be a rectangle, parallelogram, square etc. depending upon the given onditions.
 
If a cyclic quadrilateral is having base angles same, base sides are parallel and opposite sides are of same length. then it is an isosceles trapezium.
