Answer» Answer: (iii) Step-by-step explanation: For forming a triangle sum of smaller TWO sides must be greater than the third side. (i) 4+3 = 7cm and it is equal to the third side i.e.,7cm so a triangle cannot be FORMED. (ii) 10+2 = 12cm and is smaller than the third side i.e., 13 cm, THEREFORE a triangle, cannot be formed. (iii) 2+4 = 6 cm and is greater than the third side i.e., 4CM, therefore a triangle, can be formed. (IV) 7+5 = 12cm and it is equal to the third side i.e.,12cm so a triangle cannot be formed.

Answer:

(iii)

Step-by-step explanation:

For forming a triangle sum of smaller TWO sides must be greater than the third side.

(i) 4+3 = 7cm and it is equal to the third side i.e.,7cm so a triangle cannot be FORMED.

(ii) 10+2 = 12cm and is smaller than the third side i.e., 13 cm, THEREFORE a triangle, cannot be formed.

(iii) 2+4 = 6 cm and is greater than the third side i.e., 4CM, therefore a triangle, can be formed.

(IV) 7+5 = 12cm and it is equal to the third side i.e.,12cm so a triangle cannot be formed.
