Trapezoids:A pair of opposite sides is equal in trapezoid.If non-parallel pairs of opposite sides are equal then it is called as isosceles trapezium.The angles on the both sides of the base are equalThe sum of the adjacent angles are equal to 180oA trapezoid is nota parallelogramKite:The adjacent sides are equal, so it kites two pairs of equal sides. The diagonal angles is equal to 90oOne pair of opposite angle is equalThe diagonal is bisected by a longer diagonal
