Compass Geometry in Tamar Class

In our maths lesson today we learned to use a compass to make a circle and divide it into 6 sections to make a hexagon. We investigated all the different polygons that could be made by joining the centre of the circle and the points of the hexagon on the circumference. For some of us it was the first time we had used a compass and it was quite a challenge.

These are the shapes we could find: equilateral, right angled and isosceles triangle; rectangle, kite, rhombus, trapezium, inverted kite (delta), irregular pentagon, regular hexagon, irregular hexagon, inverted hexagon (chevron).

We could not find scalene triangles, regular pentagons, parallelograms, squares, heptagons octagons.
