Answer 2

Let's assume the triangle be ABC is a right

angled triangle (B=90)

AB=4cm

BC=5cm

AC=6cm

Converse of Pythagoras theorem is defined as: “If square of a side is equal to the sum of square of the other two sides then triangle must be right angle triangle''

So,AB²+BC²=AC²

4²+5²=AC²

16+25=AC²

41=AC²

AC=√41

But it (√41) contradicts the fact that AC is 6cm . So ABC is not a right angled triangle.
