Visually clear and simple, there is nevertheless a wealth of information on this poster.

The three main groups of triangle are introduced: acute angled, right angled and obtuse angled. Properties of interior and exterior angles, and of the mid point and lengths of each side are illustrated. Definitions of the circumcentre, centre of gravity, orthocentre and incentre are provided. A section is devoted to the different circles associated with the triangle: circumcircles, excircle and the many facets of the Euler line.

Lastly special triangles are introduced and a puzzle set about each: scalene, isosceles, equilateral, right and right isosceles triangles.
