Question

is it possible to construct a triangle with sides 9cm,7cm,16cm? justify your answer.

Answer 1

I think yes
it can be a scalar triangle

Answer 2

In every triangle the sum of the smallest two sides should not be more than or equal to the largest sides the sum should be smaller than the largest side

LHS. RHS

7+9 16

16. = 16

In this case the sum of the smallest two sides is equal to the largest side, therefore the triangle cannot be constructed
