About This Product

Circle theorems are easier to accept once students have seen them modelled rather than only drawn in a textbook. This one manipulative covers several results, from the general properties of a circle to the angle facts for cyclic quadrilaterals, semicircles and angles in the same segment. Rubber bands come with the ring, and the reusable storage box keeps the set together between lessons. Buyers in Papua New Guinea, North Macedonia, Laos, Kiribati, Angola and Libya can send an export enquiry for the Ring of Theorems.
