If a (hypotenuse), b (perpendicular) and c (base) are sides of a right angled triangle then the relation between them is always \[a^2+b^2=c^2\] On the screen, we see a triangle ABC in red color. Angle A will always remain 90˚ Observe how the shape of the triangle ABC changes as we change the lengths of the sides AC (b) and AB (c) using their respective slide bars.
Questions to think about Calculate \[(b^2+c^2)^{1/2} \] and compare it with side CB (a)?
