Question

The triangle have the sides 3 cm, 50 cm and 51 cm.
Is this a right-angled triangle?State whether Yes/No.

Answer 1

In the given triangle, the largest side is $51$ cm.

For a trinagle to be a right angled triangle, sum of square of its two sides must be equal to square of its third side.

$3^2+{50}^2=2509\ne {51}^2$

So the triangle is NOT a right angled triangle.
