In a right angled triangle sum of the squares of two sides is equal to the square of its third side. On the screen, we see a triangle ABC in red color. Observe how the shape of the triangle ABC changes as we change the angles α and β using their respective slide bars. (Angle A=α and Angle B=β)
Questions to think about Set α=90˚ and calculate \[AB^2+AC^2\]and compare it with \[BC^2\]? Set β=90˚ and calculate \[AB^2+BC^2\]and compare it with \[AC^2\]?
