Which of the side lengths could form a triangle? a) 2 cm, 2 cm, 4 cm b) 3 cm, 5 cm, 10 cm c) 3 cm, 4 cm, 5 cm d) 4 cm, 8 cm, 15 cm eliminate

Option C.

Step-by-step explanation:

To form a triangle we should always remember that a triangle is possible when sum of two smaller sides of the triangle is greater than the largest side.

If smaller sides are a, b and largest side is c

Then a + b > c

Now we take each option given

Option A) 2 cm, 2 cm, 4 cm

2 + 2 = 4 which equal to the largest side so to form a triangle is not possible.

Option B) 3 cm, 5 cm, 10 cm

3 + 5 = 8 < 10 cm

Here sum of smaller sides is less than to the largest side so triangle will not be formed.

Option C. 3 cm, 4 cm, 5 cm

3 + 4 = 7 > 5 cm

Therefore triangle can be formed.

Option D) 4 cm, 8 cm, 15 cm

4 + 8 = 12 < 15 cm

so triangle can not be formed.

Option C is the correct option.
