The opposite sides of a quadrilateral are parallel. If one angle of the quadrilateral is `60^0,` find the other angles.

The opposite angles of a cyclic quadrilaterals are supplimentary

If the opposite sides of a quadrilateral are equal, prove that the quadrilateral is a parallelogram.

If the opposite sides of a quadrilateral and also its diagonals are equal, then each of the angles of the quadrilateral is

Which of the following statements are true (T) and which are false (F)? In a parallelogram, the diagonals are equal. In a parallelogram, the diagonals bisect each other. In a parallelogram, the diagonals intersect each other at right angles. In any quadrilateral, if a pair of opposite sides is equal, it is a parallelogram. If all the angles of a quadrilateral are equal, it is a parallelogram. If three sides of a quadrilateral are equa, it is a parallelogram. If three angles of a quadrilateral are equal, it is a parallelogram. If all the sides of a quadrilateral are equal it is a parallelogram

A quadrilateral is parallelogram if its opposite angles are equal.
