Answer:

Hope my answer helps you mate :-)

Step-by-step explanation:

i) Because to form a triangle sum of two sides of triangle mustbe greater than third side

as 10+2=12 which is equal to 12cm side not greater.

ii) It is wrong question as it will not form right triangle according to Pythagoras theoram

as square of 11cm side is not equal to sum of square of other two side respectively.
