Sum of 4 angles of quadrilateral
Product Code : JA-MLK-4479
The Sum of 4 angles of quadrilateral set (SKU JA-MLK-4479) proves that every quadrilateral has an angle sum of 360 degrees. Its 5 parts are used to bring the four angles of a quadrilateral together around a single point, where they fill a complete turn. Pupils see directly that the four angles add up to 360 degrees, whatever the shape of the quadrilateral. The result links to the angle sum of a triangle, since a diagonal splits a quadrilateral into two triangles. JaincoLab makes this demonstration set for middle school maths labs.
