Question
Determine whether the triangle whose lengths of sides are $3 \ cm, 4 \ cm, 5 \ cm$ is a right-angled triangle.
✓
Answer
Here,
$3^2=3 \times 3=9$
$4^2=4 \times 4=16$
$5^2=5 \times 5=25$
We find $3^2+4^2=5^2$
Therefore, the triangle is right-angled.
As, we know that in any right-angled triangle, the hypotenuse happens to be the longest side. In this example, the side with length $5 \ cm$ is the hypotenuse.
