Question

4. the sides of a certain triangle
The side
given below. Find, which of them is right-triangle
16 cm, 20 cm and 12 cm
adioining figure
(ii) 6 m, 9 m and 13 m​

Answer 1

Answer:

16 cm, 20 cm and 12 cm

Step-by-step explanation:

16 cm, 20 cm and 12 cm

Answer 2

Answer:

16^2 + 12^2 = 256 + 144 = 400

which is equal to 20^2,

So, the correct answer is (i).

Step-by-step explanation:

The triangle whose sides follow the pythogorean theorem, is a right angle triangle. Acc. to the pythogorean theorem, a^2 + b^2 = c^2, where 'c' should be the Hypotenuse, i.e, the longest side, which is opp. to the right angle.

In this case, the longest side would be 20cm, hence 20^2 should be equal to the sum of the squares of the other two sides, which are 16 and 12, respectively.

Since, we can verify this by applying the pythogorean theorem on these three sides, these are the sides of a right angle triangle.

I hope you understood :)
