Text for instruction box in top of left hand side:-
We can see a triangle ABC in blue color. Angle BAC = α, angle ABC = β and angle ACB = У. Points A, B, and C are free points. Move these three points and see how the shape of the triangle, length of the sides and angles get changed

Question to think about;
1. For a given triangle, let’s arrange its sides in ascending order of their lengths. For the same triangle, let’s arrange its angles in ascending order of their values?
2. What do we observe? Which sides and angles are opposite each other?
