Question

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

12, 13, 15

Answer 1

Take a = 12, b = 13 and c = 15

Now a² + b² = 12² + 13²

= 144 + 169

= 313

15² = 225 ≠ 313

No, By the converse of Pythagoras theorem, the triangle with given measures is not a right angled triangle.
