Exterior Angle of Regular Polygon
Product Code : JA-MLI-1769
The Exterior Angle of Regular Polygon set (SKU JA-MLI-1769) demonstrates that the exterior angles of a polygon add up to 360°. It is supplied with regular polygons whose sides are extended by arms to form the exterior angles, together with a set of angle cut-outs that match each polygon. Placing the cut-outs round a single point shows that, whatever the number of sides, they always complete one full turn. JaincoLab makes this polygon exterior angles model in Ambala, India for school maths labs.
Specifications
The set consists of regular polygons with extended arms to form the exterior angles and a set of angle cut-outs matched to each polygon; the polygons included, sizes and material are confirmed on the quotation.
