Question

The sides of a triangle is given Find whether it is right
angled triangle or not. 8.,15,11​

Answer 1

By Pythagoras theorem,

altitude² + base² = hypotenuse ²

As hypotenuse is the longest side in a right angle triangle, 15 will be its measurement as it is the longest measurement given in the question.

a²+b² = c²

8²+11² = 15²

64+ 121 = 15²

185 = 15²

√185 ≠ 15

So it is not a right angled triangle.
