Jlab Export is a leading Ring of Theorems Manufacturer,and suppliers in India
Ring of Theorems (code EL-T-3699) is a circle-geometry manipulative for understanding the properties of a circle: the opposite angles of a cyclic quadrilateral, the right angle in a semicircle and the equal angles in the same segment. It comes with rubber bands and a reusable storage box. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Ring of Theorems Used For?
These are among the first circle theorems students meet: the opposite angles of a cyclic quadrilateral add up to two right angles, an angle in a semicircle is a right angle, and angles in the same segment are equal. With the rubber bands, students can form the figure for each result on the ring, change it and see which angles stay the same before they write a formal proof. The ring suits the circles chapter of class 9 mathematics and maths lab activities on circle theorems, and the reusable storage box keeps the set together between lessons.
What to Specify When Ordering
- Number of sets — often one per student pair or small group in the maths lab.
- Other geometry aids — the conic section set or Pythagoras theorem sets can be quoted on the same enquiry.
- Delivery — destination city or port and any packing or labelling needs.
Frequently Asked Questions
Which circle properties does the Ring of Theorems cover?
The opposite angles of a cyclic quadrilateral, the angle in a semicircle being a right angle, and angles in the same segment of a circle being equal.
What is supplied with it?
Rubber bands and a reusable storage box.
What does “angles in the same segment are equal” mean?
Angles formed at points on the circle by the same chord, on the same side of that chord, are all equal, wherever the points lie on that arc.
What should an export enquiry include?
The number of sets, destination country and port or city, delivery terms such as FOB or CIF, packing or labelling needs and any tender reference.
Who manufactures the Ring of Theorems?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a geometry and maths lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The ring is produced at JLab’s own works, not bought in from a trader, so schools, dealers and importers order it straight from the manufacturer, and repeat orders come from the same source. JLab exports worldwide and ships to buyers in every region — for example Jordan in the Middle East, Mexico in North America, Switzerland in Western Europe, Ivory Coast in West Africa and Denmark in Northern Europe. Tender supply information is on the JLab lab tenders page.
