Answer 1

Answer:

As we know that, in a right triangle, square of the hypotenuse is equal to the sum of square of the other two sides.

Therefore,

(39)2=(36)2+(15)2

1521=1296+225

⇒1521=1521

L.H.S. = R.H.S.

Hence the triangle is right-angled triangle.

I hope it help you

Answer 2

Answer:

It is aright angled triangle.

To prove its aright angled triangle,

(Largest side)^2 = (One small side)square + (second side square)^2

Lets take the largest side

39^2= 1521

36^2 + 15^2= 1296+225

= 1521

They are equal.

therefire, its aright angled triangle.
