No, it possible to construct a triangle with line
segments of length 5 cm , 7 cm , 12 cm .
Reason:
We can construct triangle when
sum of lenght of 2 sides of triangle is greater than third .
i.e Sum of lenght of 2 side > lenght of 3rd side .
So, here
bigger side 12
:-5 + 7 = 12
:-12 = 12
here sum of lenght of two sides of triangle is equal to lenght of third side . so we can't draw triangle .
