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 sides of equal length.
- Isosceles: It's a triangle with sides of equal length.
- Scalene: It's a triangle with sides of differing lengths.
- Not A Triangle: The given values of A, B, and C don't form a triangle.
Input Format
The TRIANGLES table is described as follows:
Each row in the table denotes the lengths of each of a triangle's three sides.
Sample Input
Sample Output
Isosceles
Equilateral
Scalene
Not A Triangle
Explanation
Values in the tuple form an Isosceles triangle, because .
Values in the tuple form an Equilateral triangle, because .
Values in the tuple form a Scalene triangle, because .
Values in the tuple cannot form a triangle because the combined value of sides and is not larger than that of side .
