S
sum of two sides should be greater than third side, I. e. 8+15=23
difference of two sides should be less than third side, I. e., 15-8=7
Hence we can form a triangle

sivaprasath: he asked about right angled triangle,but you used this technique only for forming triangle,.You should have used pythagoras theorem to find it.

Yaswanth45: he did not said that it's a right angled triangle

Yaswanth45: it's a triangle

ABHINAVrAI: BUT YOU HAVE TO CHECK IT WHETHER IT IS RIGHT ANGLED TRIANGLE OR NOT

sivaprasath: you should have used pythagoras theorem to check it,.

ABHINAVrAI: so you have to use pythagoras theorem

sivaprasath: anyway,you did 3/4 th of the answer well,.

Yaswanth45: No need

Yaswanth45: thank you

Solution:

Given: 3 sides of a triangle are 8cm,15cm & 17cm,

To find: Check whether it forms a right angled triangle or not,.

We know that, right angled triangles obey pythagoras theorem,.

(Hypotenuse(or) longest side)²=sum of the square of other two sides
                                             (17)²= (8)²+(15)²
                                              289 = 64+225
                                              289 = 289
                                             LHS = RHS
                                 ∴ Hence,it forms a right angled triangle,

                                       Hope it Helps!!
