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.

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
