What Is the Quadrilateral Angle Sum Manipulative Used For?
The angle sum property states that the four interior angles of any quadrilateral — a square, rectangle, parallelogram, trapezium or an irregular four-sided shape — add up to 360 degrees, because a diagonal divides the quadrilateral into two triangles. This manipulative makes the rule visible: the angles are separate cut-outs, and the magnet lets the teacher display them on a magnetic board for the whole group. It is used in school maths labs for geometry lessons on quadrilaterals.

Frequently Asked Questions
What does this manipulative show?
That the four angles of a quadrilateral add up to 360 degrees. The angles are provided as cut-outs from a quadrilateral.
Why does it have a magnet?
So the teacher can demonstrate it on a magnetic board, where the whole class can see it.
Is there a similar manipulative for triangles?
Yes. JLab lists an Angle Sum Property of Triangle in its Geometry range, made of cut-out angles from a triangle with a magnet at the back.
What should an export enquiry include?
The quantity, the destination country and port or city, the delivery terms you want (for example FOB or CIF), and any packing, labelling or tender requirements.
Who makes this manipulative?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its own works in Ambala, Haryana, India.
