Answer:
yes it's true
Step-by-step explanation:
To prove that any given quadrilateral is cyclic, we need to prove that its opposite angles are supplementary (i.e. they add up to 180˚). We need to prove that ∠BAD + ∠BCD = 180 and ∠ADC + ∠ABC = 180˚. ... Since the opposite angles are supplementary, an isosceles trapezium is a cyclic quadrilateral.
