What Is the Angle Sum Manipulative Used For?
The angle sum property is usually first shown by cutting the three corners off a paper triangle and placing them side by side: they fit together along a straight line, and a straight angle measures 180 degrees. This manipulative turns that activity into a durable teacher’s demonstration — the angle cut-outs hold on a magnetic board, so the whole class sees them brought together into a straight angle, and the step can be repeated without new paper each lesson. The property is part of the triangles chapter of class 7 maths and is used throughout later geometry.
What to Specify When Ordering
