1. Is a triangle formed with the side lengths 10m, 5m and 3m?

Show me the answers!

**Correct answer is option - 2**

**Explanation: **According to the triangle Inequality theorem, sum of any two sides of a triangle should always be greater than the third side.

10 + 5 = 15 > 3 Yes!

10 + 3 = 13 > 5 Yes!

5 + 3 = 8 > 10 No!

2. For a triangle to be formed with the given two side lengths 9cm, 11cm and a third side, what can be the length of the third side?

Show me the answers!

**Correct answer is option - 3**

**Explanation:**According to the triangle Inequality theorem, sum of any two sides of a triangle should always be greater than the third side.Sum of the two given sides = 9 + 11 = 20 and the only option lesser than 20 is (c).

3. For a triangle to be formed with the given two side lengths 3m, 6m and a third side, what can be the length of the third side?

Show me the answers!

**Correct answer is option - 4**

**Explanation:**According to the triangle Inequality theorem, sum of any two sides of a triangle should always be greater than the third side.Sum of the two given sides = 3 + 6= 9 and the only option lesser than 9 is (d).

4. Is a triangle formed with the side lengths 4m, 8m and 9m?

Show me the answers!

**Correct answer is option - 1**

**Explanation:**According to the triangle Inequality theorem, sum of any two sides of a triangle should always be greater than the third side.

4 + 8 = 12 > 9 Yes!

4 + 9 = 13>8 Yes!

8 + 9 = 17 > 4 Yes!

5. Is a triangle formed with the side lengths 26m, 7m and 18m?

Show me the answers!

**Correct answer is option - 2**

**Explanation:**According to the triangle Inequality theorem, sum of any two sides of a triangle should always be greater than the third side.

26 + 7 = 33 >18 Yes!

26 + 18 = 44>7 Yes!

7 + 18 = 25>26 No!
