    Cyclic quadrilateral

    Are the angle of the bolded line the same? Is a quadrilateral with two vertices touching the circumference and another two lying within the cirlcle a cyclic quadrilateral? ( I'm asked to prove that it is and I have found the angle I stated from all given information ).

    There is not enough information in the diagram to conclude that the highlighted angles are equal (If they were equal then you would have a cyclic quadrilateral, as then oposite angles would sum to two right angles)

    It would help if you posted the given information)

    Sorry Sir, but the whole diagram is too extricate and I don't have any good software to draw it.

    It is alright now, I have solved the question and my question stated above is a broken question.

    I will scan when I'm free and post the question to share with other forumers here.

    Regards.
