Check whether triangle is valid or not if sides are given in Python

PythonServer Side ProgrammingProgramming

Suppose we have three sides. We have to check whether these three sides are forming a triangle or not.

So, if the input is like sides = [14,20,10], then the output will be True as 20 < (10+14).

To solve this, we will follow these steps −

  • sort the list sides
  • if sum of first two sides <= third side, then
    • return False
  • return True

Let us see the following implementation to get better understanding −

Example Code

Live Demo

def solve(sides):
   sides.sort()
   if sides[0] + sides[1] <= sides[2]:
      return False
   return True

sides = [14,20,10]
print(solve(sides))

Input

[14,20,10]

Output

True
