Question

Which of the following triplets cannot be the angles of a triangle?

विकल्प

• 67°, 51°, 62°

• 70°, 83°, 27°

• 90°, 70°, 20°

• 40°, 132°, 18°

Answer 1

40°, 132°, 18°

Explanation:

We know that, the sum of the interior angles of a triangle is 180°.

Now, we will verify the given triplets:

1. 67° + 51° + 62° = 180°
2. 70° + 83° + 27° = 180°
3. 90° + 70° + 20° = 180°
4. 40° + 132° + 18° = 190°

Clearly, triplets in 40°, 132°, 18° cannot be the angles of a triangle.
