Ring of Theorems
Product Code : JA-MLI-1853
The Ring of Theorems (SKU JA-MLI-1853) is used to understand the properties of a circle through hands-on work with rubber bands. Stretching bands between points on the ring, students form cyclic quadrilaterals and angles, and see that opposite angles of a cyclic quadrilateral are supplementary, that the angle in a semicircle is a right angle and that angles in the same segment of a circle are equal. It is supplied with rubber bands and a reusable storage box. JaincoLab makes this circle theorems kit in Ambala, India.

Exploring circle theorems with the ring
Because the bands can be moved between points, students test each theorem on several figures and see that the result always holds.
- Opposite angles of a cyclic quadrilateral
- Angle in a semicircle is a right angle
- Angles in the same segment are equal
- Angles at the centre and on the circumference
- Group investigations before formal proofs
