The students of classes IX A , B , C performed a lab activity on inequalities of triangles where they verified that any given figure is a triangle only if “ the sum of two sides of the triangle is greater than the third side “ and “ the difference of two sides of triangle is smaller than the third side”. This activity helped them in better understanding of the concept of proving a figure to be a triangle.
Learning Objective :- 1. To establish a relation between the largest side and the sum of other two sides of a triangle.
2. Prove or disprove a figure to be a triangle.
3. Enhancing their thinking and analytical skills.
Class IX
