Given sides are 15 cm, 39 cm, and 36 cm.

So if 15² + 36² = 39² then it is a right angled triangle.

15² + 36² = 225 + 1296
= 1521

39² = 1521

Here hypotenuse² = side² + side²

so it is a right angled triangle.

hope it helps!!!☺️

Answer 2

since for the triangle to be right angled it should follow the Pythagoras theorem ..
according to Pythagoras theorem..
hypotenuse^2 = base ^2+perpendicular^2
then
${39}^{2} should \: be \: equal \: to \: {15}^{2} + {36}^{2} \\ then \: 39 \times 39 = 1521 \\ {15}^{2} + {36}^{2} = 225 + 1296 = 1521$
