it has to be between 4 and 24.... that's the sum/difference of the two other sides of the face.

anonymous · Answer

3rd side of a triangle can't be equal to or smaller than the difference of other two sides, and it can't be equal to and greater than the sum of the other two sides.

anonymous · Answer

So, in this case, it has to be between (14-10) and (14+10).

anonymous · Answer

okay thanks

anonymous · Answer

if the third side is 4 wouldn't it be incorrect. because 4+10=14 which is = to the first side
