Question

side of non parallel side of trapezium are equal prove that it is a cyclic
​

Answer 1

If the non-parallel sides of a trapezium are equal, prove that it is cyclic. Given: $$ABCD$$ is a trapezium where non-parallel sides AD and BC are equal. ... Thus, $$ABCD$$ is a cyclic quadrilateral as sum of the pair of opposite angles is $$180°$$.
