Angle Sum Property of Triangle
Product Code : JA-G-3569
The Angle Sum Property of Triangle kit (SKU JA-G-3569) teaches that the three angles of a triangle add up to 180 degrees. It provides a triangle with its angles as separate cut-outs and a magnet on the back, so the teacher can work on a magnetic board, placing the three angle pieces side by side along a straight line to show that they make 180 degrees. This triangle angle sum kit suits primary and middle school geometry. JaincoLab manufactures it.
Specifications
The kit consists of a triangle with cut-out angle pieces, backed with magnets for demonstration on a magnetic board; triangle size, material and the number of triangles are confirmed on the quotation.

Applications of the triangle angle sum kit
On a magnetic board the teacher removes the three angle cut-outs and places them together at one point along a straight line, so the class sees that they fill a straight angle, and pupils then apply the rule to find missing angles.
- Showing that triangle angles sum to 180 degrees
- Straight angle and angles on a line
- Finding a missing angle in a triangle
- Whole-class demonstration on a magnetic board
- Maths lab activity for primary and middle school
