Jlab Export is a leading Sum of 3 angles of triangle Manufacturer,and suppliers in India
Sum of 3 angles of triangle (code EL-MLK-4478) is a magnetic set of 4 parts for classroom demonstration, used by maths teachers to prove the angle sum property of a triangle — that its three interior angles always add up to 180°. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Sum of 3 Angles of Triangle Set Used For?
The angle sum property is one of the first theorems pupils meet in geometry, and the classic hands-on proof brings the three angles of a triangle together at one point, where they form a straight angle. Because this set is magnetic and made for classroom demonstration, the teacher can carry out the proof in front of the whole class in middle-school maths lessons or the school maths lab.
What to Specify When Ordering
- Quantity — the number of sets for your maths classrooms or lab.
- Companion theorem sets — for example the quadrilateral angle-sum aids listed below, which can go on the same enquiry.
- Delivery — the destination and, for export, the delivery terms you prefer.
Frequently Asked Questions
What does this set prove?
That the three angles of any triangle add up to 180°, a straight angle. It is a magnetic set of 4 parts designed for classroom demonstration of that principle.
How is it different from the Angle Sum Property of Triangle?
Both are magnetic teaching aids for the same property. This one is a set of 4 parts; the Angle Sum Property of Triangle is made of cut-out angles from a triangle with a magnet at the back, for use on a magnetic board.
What information is needed for an export quotation?
The quantity, the destination country and port or city, the delivery terms you want (FOB or CIF, for example), packing or labelling requirements and any tender reference.
Who makes this geometry set?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, at its own works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maths lab and science equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Its geometry demonstration sets are made in-house rather than bought from traders, so schools, colleges, dealers and importers deal directly with the factory, every set gets a visual inspection before dispatch, and repeat orders are handled by the maker. JLab exports worldwide and ships to buyers in every region — for example Lebanon in the Middle East, Mexico in North America, Hungary in Eastern Europe, Gabon in Central Africa and Mongolia in East Asia. For school and government purchases, see the JLab lab tenders page.
Other Angle and Triangle Theorem Aids
- Angle Sum Property of Triangle — magnetic cut-out angles from a triangle, with a magnet at the back.
- Sum of 4 angles of quadrilateral — a set of 5 parts to prove that the angles of any quadrilateral total 360°.
- Angle Sum Property of Quadrilateral — magnetic cut-out angles from a quadrilateral.
- Finding the Incenter of different types of triangles — a magnetic set with right-angled, acute, obtuse and equilateral triangles.
