Question

The sides of triangle is given below. Determine it is right triangle or not.

a = 9 cm, b = l6 cm and c = 18 cm

Answer 1

We have,

a = 9 cm, b = 16 cm and c = 18 cm

∴ a² = 81, b² = 256 and c² = 324

Since, a² + b² = 81 + 256 = 337

≠ c²

Then, by converse of Pythagoras theorem, given triangle is not a right triangle.
