For space any space triangle comma space the space sum space of space the space lengths space of space any space two space sides space should space be space greater space than space the space third space side. In space Isosceles space triangle comma space two space sides space are space equal. That space means space the space length space of space the space third space side space can space be space 5 space or space 11. Consider space length space of space third space side space as space 5. Then comma space we space have 5 plus 5 equals 10 less than 11 comma space which space is space not space possible Consider space length space of space third space side space as space 11. Then comma space we space have 11 plus 11 equals 22 greater than 5 space and space 11 plus 5 equals 16 greater than 11 Hence comma space the space length space of space third space side space is space 11 space cm.
