Question

Determine if its possible to form a triangle using the set of segments with the given measurement. explain please! 12 m, 5 m, 18.9 m

Answer 1

Adding together the shorter two sides results in 17 m. If these two sides were laid end to end, the sum of their sides (17 m) would be less than the length of the third side. Thus, NO triangle could be constructed with this set of line segments.
