Ring of Theorems
Product Code : JA-T-3699
The Ring of Theorems (SKU JA-T-3699) is a circle theorems ring kit supplied with rubber bands and a reusable storage box. Pupils stretch the bands between points on the ring to form chords, triangles and cyclic quadrilaterals, then compare the angles they make, to explore the properties of the circle. It suits secondary geometry lessons and maths lab activities, and JaincoLab manufactures it.

Applications of the circle theorems ring kit
By moving the rubber bands to new points on the ring, pupils make many versions of the same figure quickly and see that the angle relationships stay the same, which builds confidence before formal proofs.
- Properties of the circle
- Opposite angles of a cyclic quadrilateral
- The angle in a semicircle is a right angle
- Angles in the same segment of a circle are equal
- Pair and group activities with rubber bands
