How can you represent the curvature of a cylinder on a flat piece of paper?

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

Generate three random numbers to determine the side lengths of a triangle. What triangles can you draw?

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

Describe how to construct three circles which have areas in the ratio 1:2:3.

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

Construct a line parallel to one side of a triangle so that the
triangle is divided into two equal areas.

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

Design and construct a prototype intercooler which will satisfy agreed quality control constraints.

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

Construct this design using only compasses

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

The diagonal of a square intersects the line joining one of the unused corners to the midpoint of the opposite side. What do you notice about the line segments produced?

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

What shape and size of drinks mat is best for flipping and catching?

##### Age 7 to 16 Challenge Level:

Explore patterns based on a rhombus. How can you enlarge the
pattern - or explode it?

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

What fractions can you divide the diagonal of a square into by simple folding?

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

Prove that, given any three parallel lines, an equilateral triangle
always exists with one vertex on each of the three lines.

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

You are only given the three midpoints of the sides of a triangle. How can you construct the original triangle?

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

Draw a line (considered endless in both directions), put a point
somewhere on each side of the line. Label these points A and B. Use
a geometric construction to locate a point, P, on the line,. . . .

##### Age 7 to 16 Challenge Level:

The challenge is to produce elegant solutions. Elegance here implies simplicity. The focus is on rhombi, in particular those formed by jointing two equilateral triangles along an edge.

##### Age 7 to 14

Jenny Murray describes the mathematical processes behind making patchwork in this article for students.

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

Have a go at creating these images based on circles. What do you notice about the areas of the different sections?

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

Here is a chance to create some attractive images by rotating shapes through multiples of 90 degrees, or 30 degrees, or 72 degrees or...

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

Medieval stonemasons used a method to construct octagons using ruler and compasses... Is the octagon regular? Proof please.

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

Using a ruler, pencil and compasses only, it is possible to
construct a square inside any triangle so that all four vertices
touch the sides of the triangle.

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

Drawing a triangle is not always as easy as you might think!
