L4 How many different congruent tiles can you find (needn't be letters) ? Change the outline - eg: (page of these provided) Can you describe how to transform the shaded shape into the white one? Eg reflect and translate, rotate... Teacher's Notes Topic: Congruence, transformations Show how the two congruent 'F-tiles' can fit together to make this shape. (a) The diagram shows how two congruent 'F-tiles' fit together to make a rectangle. Fitting tiles What other shape could the tiles be? Show them on the diagram. (b) Two other tiles fit together to make a different shape. The two tiles are congruent but they are not 'F- tiles'. What shape could the tiles be? Show them on the diagram.

Fitting tiles (a) The diagram shows how two congruent 'F-tiles' fit together to make a rectangle. Show how the two congruent 'F-tiles' can fit together to make this shape.

(b) Two other tiles fit together to make a different shape. The two tiles are congruent but they are not 'F- tiles'. What shape could the tiles be? Show them on the diagram. What other shape could the tiles be? Show them on the diagram.
