Intersection of diagonals (2) ABCD is a cyclic quadrilateral if and only if points P and Q are the midpoints of sides AB and CD. The intersection P may be internal or external to the circle. In the former case, the cyclic quadrilateral is ABCD, and in the latter case, the cyclic quadrilateral is ABDC.

A rhombus is a quadrilateral (plane figure, closed shape, four sides) with four equal-length sides and opposite sides parallel to each other. All rhombuses are parallelograms, but not all parallelograms are rhombuses. All squares are rhombuses, but not all rhombuses are squares.

In Euclidean geometry, a cyclic quadrilateral or inscribed quadrilateral is a quadrilateral whose vertices all lie on a single circle. This circle is called the circumcircle or circumscribed circle, and the vertices are said to be concyclic. ... An example of a quadrilateral that cannot be cyclic is a non-square rhombus.

Solution. Here, ABCD is a cyclic quadrilateral, we need to find x. In cyclic quadrilateral the sum of opposite angles is equal to 180°. Hence, the value of x is 100°.

Rhombus is a quadrilateral with all four sides equal in length. A rhombus is actually just a special type of parallelogram (just like square or rectangle). So ABCD is a rhombus means AB=BC=CD=AD.

If all sides of a quadrilateral are congruent, then it's a rhombus (reverse of the definition). If the diagonals of a quadrilateral bisect all the angles, then it's a rhombus (converse of a property).

Thus, "line segments AC and BD are perpendicular bisectors of each other" means that AC cuts BD into two equal parts at 90° and BD cuts AC into two equal parts at 90°. For (2): AB = BC = CD = AD, means that ABCD is either a rhombus or square (so still a rhombus).
