Presentation transcript:

A parallelogram has opposite sides and opposite angles equal.

A square and a rhombus have diagonals that bisect at right angles.

A kite and an isosceles trapezium have diagonals that are equal in length.

Some rhombuses are squares.

The diagonals of a parallelogram cross perpendicularly.

A kite and a rhombus have diagonals that bisect the angles.

Some quadrilaterals are trapeziums.

All kites are quadrilaterals.

All quadrilaterals are parallelograms.

All rectangles are squares.

All rhombuses are parallelograms but a parallelogram is not necessarily a rhombus.

A rhombus can never be split into two equilateral triangles.
