Quadrilaterals

The large rectangle is divided into a series of smaller quadrilaterals and triangles. Can you untangle what fractional part is represented by each of the shapes?

What does the overlap of these two shapes look like? Try picturing it in your head and then use some cut-out shapes to test your prediction.

Explore when it is possible to construct a circle which just touches all four sides of a quadrilateral.

If you split the square into these two pieces, it is possible to fit the pieces together again to make a new shape. How many new shapes can you make?

Players take it in turns to choose a dot on the grid. The winner is the first to have four dots that can be joined to form a square.
