A cyclic trapezium is isoceless and its diagonal are equal.

If two sides of a cyclic quadrilateral are parallel,prove that the remaining two sides are equal and the diagonals are also equal.OR A cyclic trapezium is isosceles and its diagonals are equal.

ABCD is a trapezium in which ABIDC and its diagonals intersect each other at the point 0. Show that (AO)/(BO)=(CO)/(DO)

An angle of a cyclic trapezium is twice the other angle. Find the value of the smaller angle.

ABCD is a cyclic trapezium whose side AD and BC are parallel to each other. If angle ABC=62^(@) then the measure of the angleBCD is :

If the two sides of a pair of opposite sides of a cyclic quadrilateral are equal,prove that its diagonals are equal.

Isosceles trapezium a trapezium is said to be an isosceles trapezium if its non-parallel sides are equal.
