Answer:
The correct answer would be 3 cm, 4cm, and 5 cm
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.
