In the given triangle, the largest side is 6 cm.
We know that in a right angled triangle, the sum of the squares of the smaller sides should be equal to the square of the largest side.
Therefore,
32 + 42 = 9 + 16 = 25
But, 62 = 36
32 + 42 = 25 which is not equal to 62
Hence, the given triangle is not a right angled triangle.
