Question

Check whether given sides are the sides of right-angled triangles, using Pythagoras theorem

9, 40, 41

Answer 1

Take a = 9, b = 40 and c = 41

Now a² + b² = 9² + 40²

= 81 + 1600

= 1681

c² = 41² = 1681

∴ a² + b² = c²

Yes, By the converse of Pythagoras theorem, the triangle with given measures is a right angled triangle.
