TANGRAM SET   Our Price: £4.50

 TANGRAM SET

These brightly-coloured plastic geometric puzzle sets include one tangram each in red, blue, yellow and green. 

In 1942 Fu Tsiang Wang and Chuan-chin Hsiung mathematically proved that there were a finite set of patterns referred to as 'convex', in other words shapes that had no indentations along the outside edge, that could be made with a tangram. There are only 13 silhouettes that qualify. Can you work them all out or even prove that there are more?
