Question 3 Nested If-Else Triangle Classification

Check if Sides Form a Triangle and Classify Type

Write a Python program to take three side lengths as input. First verify if a valid triangle can be formed using the triangle inequality theorem; if valid, use nested conditions to classify it as Equilateral, Isosceles, or Scalene.
