Question

check if a triangle of given sides is a right triangle or not side is 6 9 12​

Answer 1

Hey there!

Answer:

No, the given triangle isn't right angled triangle.

Step-by-step explanation:

We can check it by verifying Pythagoras theorem which states that the square of longest side i.e Hypotenuse is equal to squares of other two sides i.e Base and perpendicular.

H² = B² + P²

(12)² = 6² + 9²

144 = 36 + 81

144 = 117

L.H.S ≠ R.H.S

Hence, it is not a right angled triangle.

Answer 2

Answer:

No. It is not a right angled triangle.

Step-by-step explanation:

It will be a right angled triangle if the square of its longest side equals the sum of the squares of its two other sides, according to the pythagoras theorem.

So, here, the longest side is 12 units.

12² = 144

The two other sides are 6 units and 9 units.

6² = 36

9² = 81

36 + 81 = 117

But, 117 is not equal to 144.

Thus, a triangle with sides 6, 9, 12 units is not a right angled triangle.
