The TRAPEZIUM Discuss and write down the properties of a trapezium with your friend.

The TRAPEZIUM One pair of opposite sides are parallel

The TRAPEZIUM One pair of opposite sides are parallel MAIN MENU END SHOW

The PARALLELOGRAM The PARALLELOGRAM Draw a parallelogram and try to find as many of its properties as you can.

The PARALLELOGRAM Opposite sides are equal Opposite sides are parallel Opposite angles are equal Diagonals bisect each other

The PARALLELOGRAM Opposite sides are equal Opposite sides are parallel Opposite angles are equal Diagonals bisect each other MAIN MENU END SHOW

The RHOMBUS The RHOMBUS Draw a rhombus of side 6 cm and discuss the properties of the rhombus with your friend (you can use a dictionary if you want).

The RHOMBUS The RHOMBUS All sides are equal Opposite sides are parallel Opposite angles are equal Diagonals bisect each other at 90°

The RHOMBUS The RHOMBUS All sides are equal Opposite sides are parallel Opposite angles are equal Diagonals bisect each other at 90° MAIN MENU END SHOW

The RECTANGLE The RECTANGLE How many properties belonging to the rectangle can you find?

The RECTANGLE The RECTANGLE Opposite sides are equal Opposite sides are parallel All angles are right angles (90o) Diagonals are equal and bisect one another

The RECTANGLE The RECTANGLE Opposite sides are equal Opposite sides are parallel All angles are right angles (90o) Diagonals are equal and bisect one another MAIN MENU END SHOW

The SQUARE The SQUARE Play a game with your friend. In one minute each of you must write as many properties the square has on a piece of paper. The one with the greatest number of correct properties is the WINNER.

The SQUARE The SQUARE All sides are equal Opposite sides are parallel All angles are right angles (90o) Diagonals are equal and bisect one another at right angles

The SQUARE The SQUARE All sides are equal Opposite sides are parallel All angles are right angles (90o) Diagonals are equal and bisect one another at right angles MAIN MENU END SHOW
