Hello coders, In this post, you will learn how to solve the Type of Triangle Hacker Rank Solution. This problem is a part of the SQL Hacker Rank series.
Write a query identifying the type of each record in the TRIANGLES table using its three side lengths. Output one of the following statements for each record in the table:
- Equilateral: It’s a triangle with 3 sides of equal length.
- Isosceles: It’s a triangle with 2 sides of equal length.
- Scalene: It’s a triangle with 3 sides of differing lengths.
- Not A Triangle: The given values of A, B, and C don’t form a triangle.
The TRIANGLES table is described as follows:
Each row in the table denotes the lengths of each of a triangle’s three sides.
Isosceles Equilateral Scalene Not A Triangle

select if(A+B<=C or B+C<=A or A+C<=B,"Not A Triangle", if(A=B and B=C,"Equilateral", if(A=B or B=C or A=C,"Isosceles","Scalene"))) from TRIANGLES as T;
