One angle of a quadrilateral is of 108º and the remaining three angles are equal. Find each of the three equal angles.

ABCD is a trapezium in which AB || DC and ∠A = ∠B = 45º. Find angles C and D of the trapezium.

In a parallelogram, opposite angles are:

The angle between two altitudes of a parallelogram through the vertex of an obtuse angle of the parallelogram is 60º. Find the angles of the parallelogram.

Three angles of a quadrilateral are 75º, 90º and 75º. The fourth angle is

If angles A, B, C and D of the quadrilateral ABCD, taken in order, are in the ratio 3:7:6:4, then ABCD is a

The consecutive angles of a parallelogram are

ABCD is a rhombus such that ∠ACB = 40º. Then ∠ADB is

The diagonals of a parallelogram:

If in a parallelogram its diagonals bisect each other and are equal then it is a,

If ABCD is a trapezium in which AB || CD and AD = BC, then:
