Can it form a triangle?

Question

How to develop a python program that reads the length of three lines and tells whether or not they can form a triangle?

Answer 1

It is a geometric question. If every sum of length of two lines are bigger than third line, then it is possible to draw a triangle. Code is look like:
A = float(input ())
B = float (input ())
C = float (input ())
If A+B > C and A+C> B and B + C > A:
Print("It is possible")
Else:
Print ("Is is impossible")
