Question

Find whether the sides of the triangle as given below form a right-triangled or not, $8$ cm, $15$ cm and $17$ cm

Answer 1

In a right angled triangle, sum of squares of two sides should be equal to the square of the third side.
Here, $8^2=64$

${15}^2=225$

${17}^2=289$
Since, $64+225=289$, the sides form a right angled triangle.
