How many questions do you need to identify my quadrilateral?

##### Age 11 to 16 Challenge Level:

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.

##### Age 11 to 14 Challenge Level:

Charlie and Alison have been drawing patterns on coordinate grids. Can you picture where the patterns lead?

##### Age 14 to 16 Challenge Level:

Is there a relationship between the coordinates of the endpoints of a line and the number of grid squares it crosses?

##### Age 14 to 16 Challenge Level:

In this problem we are faced with an apparently easy area problem,
but it has gone horribly wrong! What happened?

##### Age 11 to 14 Challenge Level:

Can you describe this route to infinity? Where will the arrows take you next?

##### Age 11 to 14 Challenge Level:

It's easy to work out the areas of most squares that we meet, but
what if they were tilted?

##### Age 7 to 14 Challenge Level:

Can you find a reliable strategy for choosing coordinates that will locate the treasure in the minimum number of guesses?

##### Age 11 to 14 Challenge Level:

Can you recreate squares and rhombuses if you are only given a side
or a diagonal?

##### Age 7 to 14 Challenge Level:

On the graph there are 28 marked points. These points all mark the vertices (corners) of eight hidden squares. Can you find the eight hidden squares?

##### Age 14 to 16 Challenge Level:

Polygons drawn on square dotty paper have dots on their perimeter (p) and often internal (i) ones as well. Find a relationship between p, i and the area of the polygons.

##### Age 14 to 18 Challenge Level:

Some treasure has been hidden in a three-dimensional grid! Can you work out a strategy to find it as efficiently as possible?

##### Age 14 to 16 Challenge Level:

Can you find the area of a parallelogram defined by two vectors?

##### Age 11 to 14 Challenge Level:

A tilted square is a square with no horizontal sides. Can you
devise a general instruction for the construction of a square when
you are given just one of its sides?

##### Age 14 to 18 Challenge Level:

Charlie likes to go for walks around a square park, while Alison likes to cut across diagonally. Can you find relationships between the vectors they walk along?

##### Age 11 to 14 Challenge Level:

We started drawing some quadrilaterals - can you complete them?
