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
Solution
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.
