Question

prove that sum of two sides of a triangle is greater than third side

Answer 1

this may not be applicable to all triangles but if we add the two angle we can find the angle of the third one will be more

Answer 2

A+B > C
B+C> A

A+C>B
          FOR eg : 10 +3 > 4

 10+4 >3 

3+4> 10       SO THIS PROVE THAT THE THIRD SIDE OF THE TRIANGLE WILL BE LESSTHAN THE SUM OF SIDES
