About This Product

Tearing the corners off a paper quadrilateral and fitting them round a point is a classic way to prove the angle sum, and this resource makes the same activity repeatable. The angle pieces fit together around one point to form a complete turn, and the magnetic backing lets a teacher show each step on the board for the whole class, alongside other maths lab instruments.

Frequently Asked Questions

Can it be shown on a board for the class to see?

Yes. It has a magnet on the back, so it can be demonstrated on a magnetic board.
