Answer 1

Answer:

ur answer is 1

2cm 2cm 4cm

Answer 2

Answer:

10,11,12

Step-by-step explanation:

See, if you want to construct a triangle, the largest side should be smaller than the sum of the other two sides

1) Here, 4 is the largest side

2+2=4. So, the largest side is not smaller than sum of other two sides and hence the triangle cannot be constructed.

2) 10+11<12

The triangle can be constructed.

3) 3+4=7 so triangle cannot be constructed.

Hope this helps
